	The accompanying interim consolidated balance sheet and statement of stockholders’ equity as of March 31, 2015, and the related statements of comprehensive loss and cash flows for the three months ended March 31, 2015 and 2014 are unaudited. The unaudited consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been omitted.
	In the opinion of management, the accompanying unaudited consolidated financial statements for the periods presented reflect all adjustments, which are normal and recurring, necessary to fairly state the financial position, results of operations and cash flows. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 filed with the SEC on February 27, 2015.
	Intercompany balances and transactions have been eliminated in consolidation.
	Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2015.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	3. Recent Accounting Pronouncements
	In August 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40). The Update provides U.S. GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The amendments in this Update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The amendments to this Update supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of this Topic is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. This Topic defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. For all entities, the amendments in this Update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. Earlier adoption is not permitted. An entity will be able to use either of two adoption methods: (1) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within this Topic; or (2) retrospective with the cumulative effect of initially applying this Topic recognized at the date of initial application and providing certain additional disclosures as defined per this Topic. We will be evaluating the impact of this guidance on our consolidated financial statements.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	4. Net Income (Loss) Per Share
	The Company calculates earnings per share (“EPS”) as required by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 260, Earnings Per Share. Basic EPS is calculated by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period, excluding common stock equivalents. Diluted EPS is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period plus the weighted average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method. For periods with a net loss, the dilutive common stock equivalents are excluded from the diluted EPS calculation. For purposes of this calculation, common stock subject to repurchase by the Company and options are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive.

Fair_Value_of_Financial_Instru

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	6. Fair Value of Financial Instruments
	The Company measures and discloses fair value measurements as required by FASB ASC Topic No. 820, Fair Value Measurements and Disclosures.
	The carrying value of accounts receivable, foreign cash accounts, prepaid expenses, other current assets, accounts payable, and accrued expenses are considered to be representative of their respective fair values because of the short-term nature of those instruments.
	Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, the FASB establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:
		•	Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
		•	Level 2 - Include other inputs that are directly or indirectly observable in the marketplace.
		•	Level 3 - Unobservable inputs which are supported by little or no market activity.
	The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
	As required by FASB ASC Topic No. 820, we measure our cash equivalents and short-term investments at fair value. Our cash equivalents and short-term investments are classified within Level 1 by using quoted market prices utilizing market observable inputs.
	As required by FASB ASC Topic No. 825, Financial Instruments, an entity can choose to measure at fair value many financial instruments and certain other items that are not currently required to be measured at fair value. Subsequent changes in fair value for designated items are required to be reported in earnings in the current period. This Topic also establishes presentation and disclosure requirements for similar types of assets and liabilities measured at fair value. As permitted, the Company has elected not to use the fair value option to measure our available-for-sale securities under this Topic and will continue to report as required by FASB ASC Topic No. 320, Investments-Debt and Equity Securities. We have made this election because the nature of our financial assets and liabilities are not of such complexity that they would benefit from a change in valuation to fair value.

	Cash and cash equivalents generally consist of cash, government securities, mutual funds, and money market funds. These securities are primarily held in two financial institutions and are uninsured except for the minimum Federal Deposit Insurance Corporation (“FDIC”) coverage, and have original maturity dates of three months or less. As of March 31, 2015 and December 31, 2014, bank balances totaling approximately $9.7 million and $9.9 million, respectively, were uninsured.

	Short-term investments consist of U.S. government agency and government sponsored enterprise obligations. The Company accounts for these short-term investments as required by FASB ASC Topic No. 320, Investments-Debt and Equity Securities. These debt and equity securities are not classified as either held-to-maturity securities or trading securities. As such, they are classified as available-for-sale securities. Available-for-sale securities are recorded at fair value, with unrealized gains or losses recorded as a separate component of accumulated other comprehensive income in stockholders’ equity until realized. Available-for-sale securities with contractual maturities of less than 12 months were as follows (in thousands):

	Segment Information
	Public companies are required to report financial and descriptive information about their reportable operating segments as required by FASB ASC Topic No. 280, Segment Reporting. The Company has two primary business units based on how management internally evaluates separate financial information, business activities and management responsibility. Wireless includes our QuickLink®, NetWise® and CommSuite® family of products. Productivity & Graphics includes our consumer-based products: Poser®, Anime Studio®, Manga Studio®, MotionArtist® and StuffIt®.
	The Company does not separately allocate operating expenses to these business units, nor does it allocate specific assets. Therefore, business unit information reported includes only revenues.
	The following table shows the revenues generated by each business unit (in thousands):

	The Company leases its buildings under operating leases that expire on various dates through 2022. Future minimum annual lease payments under such leases as of March 31, 2015 are as follows (in thousands):
	Year Ending December 31,	Operating

	Total	$	11,161
	As of March 31, 2015, $5.4 million of the remaining lease commitments expense has been accrued as part of the 2013 Restructuring Plan, partially offset by future estimated sublease income of $2.8 million.
	Rent expense under operating leases was $0.3 million for both the three months ended March 31, 2015 and 2014.
	As a condition of our Pittsburgh lease that was signed in November 2010, the landlord agreed to incentives of $40.00 per square foot, or a total of $2.2 million, for improvements to the space. These costs have been included in deferred rent in our long-term liabilities and are being amortized over the ten year lease term.
	Pennsylvania Opportunity Grant Program
	On September 26, 2011, we received $1.0 million from the State of Pennsylvania to help fund our agreement to start-up a new facility. The grant carried with it an obligation, or commitment, to employ at least 232 people within a three-year time period that ended on December 31, 2013. We received an extension of time to meet this employment commitment. The new deadline was February 28, 2015. We have requested another extension. This grant contains conditions that would require us to return a pro-rata amount of the monies received if we fail to meet these conditions. As such, the monies have been recorded as a liability in the accrued liabilities line item on the balance sheet until we are irrevocably entitled to retain the monies, or until it is determined that we need to return a portion or all of the monies received.
	Litigation
	The Company may become involved in various legal proceedings arising from its business activities. While management does not believe the ultimate disposition of these matters will have a material adverse impact on the Company’s consolidated results of operations, cash flows or financial position, litigation is inherently unpredictable, and depending on the nature and timing of these proceedings, an unfavorable resolution could materially affect the Company’s future consolidated results of operations, cash flows or financial position in a particular period.
	Other Contingent Contractual Obligations
	During its normal course of business, the Company has made certain indemnities, commitments and guarantees under which it may be required to make payments in relation to certain transactions. These include: intellectual property indemnities to the Company’s customers and licensees in connection with the use, sale and/or license of Company products; indemnities to various lessors in connection with facility leases for certain claims arising from such facility or lease; indemnities to vendors and service providers pertaining to claims based on the negligence or willful misconduct of the Company; indemnities involving the accuracy of representations and warranties in certain contracts; and indemnities to directors and officers of the Company to the maximum extent permitted under the laws of the State of Delaware. In addition, the Company has made contractual commitments to employees providing for severance payments upon the occurrence of certain prescribed events. The Company may also issue a guarantee in the form of a standby letter of credit as security for contingent liabilities under certain customer contracts. The duration of these indemnities, commitments and guarantees varies, and in certain cases, may be indefinite. The majority of these indemnities, commitments and guarantees may not provide for any limitation of the maximum potential for future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities, commitments and guarantees in the accompanying consolidated balance sheets.

Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes
	We account for income taxes as required by FASB ASC Topic No. 740, Income Taxes. This Topic clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Topic also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Topic requires an entity to recognize the financial statement impact of a tax position when it is more likely than not that the position will be sustained upon examination. The amount recognized is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. In addition, the Topic permits an entity to recognize interest and penalties related to tax uncertainties either as income tax expense or operating expenses. The Company has chosen to recognize interest and penalties related to tax uncertainties as income tax expense.
	The Company assesses whether a valuation allowance should be recorded against its deferred tax assets based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether deferred tax assets will be realized are: (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax liabilities against gross deferred tax assets); (2) taxable income in prior carryback years, if carryback is permitted under the applicable tax law; (3) tax planning strategies and (4) future taxable income exclusive of reversing temporary differences and carryforwards.
	In assessing whether a valuation allowance is required, significant weight is to be given to evidence that can be objectively verified. A significant factor in the Company’s assessment is that the Company has been in a four-year historical cumulative loss as of the end of fiscal year 2014. These facts, combined with uncertain near-term market and economic conditions, reduced the Company’s ability to rely on projections of future taxable income in assessing the realizability of its deferred tax assets.
	After a review of the four sources of taxable income as of December 31, 2014 (as described above), and after consideration of the Company’s continuing cumulative loss position as of December 31, 2014, the Company will continue to reserve it’s U.S.-based deferred tax amounts, which total $75.7 million, as of March 31, 2015.
	The Company is subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. Federal income tax returns of the Company are subject to IRS examination for the 2012 and 2013 tax years. State income tax returns are subject to examination for a period of three to four years after filing. The outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income tax in the period such resolution occurs. We may from time to time be assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to our financial results. It is the Company’s policy to classify any interest and/or penalties in the financial statements as a component of income tax expense.

Restructuring and Related Activities [Abstract]
Restructuring Expenses	14. Restructuring Expenses
	2014 Restructuring
	On May 6, 2014, the Board of Directors approved a plan of restructuring intended to streamline and flatten the Company’s organization, reduce overall headcount by approximately 20% and reduce its overall cost structure by approximately $2.0 million per quarter. The restructuring plan resulted in special charges totaling $1.8 million recorded during the three month period ended June 30, 2014. These charges were for non-cash stock-based compensation expense of $1.3 million, severance costs for affected employees of $0.4 million, and other related costs of $0.1 million.
	2013 Restructuring
	On July 25, 2013, the Board of Directors approved a plan of restructuring intended to bring the Company’s operating expenses better in line with revenues. The restructuring plan involved a realignment of organizational structures, facility consolidations/closures and headcount reductions of approximately 26% of the Company’s worldwide workforce. The restructuring plan was implemented primarily during the three month period ended September 30, 2013 and resulted in annualized savings of approximately $16.0 million.
	The restructuring plan resulted in special charges totaling $5.6 million recorded in the year ended December 31, 2013. These charges were for lease/rental terminations of $3.3 million, severance costs for affected employees of $1.1 million, equipment and improvements write-offs as a result of our lease/rental terminations of $1.0 million and other related costs of $0.2 million.
	In the year ended December 31, 2014, we increased the reserve by $0.6 million due to changes in our assumptions on future sublease income on our lease terminations of $0.8 million, partially offset by adjustments to our one-time employee termination benefits.
	Following is the activity in our restructuring liability account for the period ended March 31, 2015 (in thousands):

Basis of Presentation	Basis of Presentation
	The accompanying interim consolidated balance sheet and statement of stockholders’ equity as of March 31, 2015, and the related statements of comprehensive loss and cash flows for the three months ended March 31, 2015 and 2014 are unaudited. The unaudited consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been omitted.
	In the opinion of management, the accompanying unaudited consolidated financial statements for the periods presented reflect all adjustments, which are normal and recurring, necessary to fairly state the financial position, results of operations and cash flows. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 filed with the SEC on February 27, 2015.
	Intercompany balances and transactions have been eliminated in consolidation.
	Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2015.
Recent Accounting Pronouncements	In August 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40). The Update provides U.S. GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The amendments in this Update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The amendments to this Update supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of this Topic is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. This Topic defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. For all entities, the amendments in this Update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. Earlier adoption is not permitted. An entity will be able to use either of two adoption methods: (1) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within this Topic; or (2) retrospective with the cumulative effect of initially applying this Topic recognized at the date of initial application and providing certain additional disclosures as defined per this Topic. We will be evaluating the impact of this guidance on our consolidated financial statements.
Net Income (Loss) Per Share	Net Income (Loss) Per Share
	The Company calculates earnings per share (“EPS”) as required by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 260, Earnings Per Share. Basic EPS is calculated by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period, excluding common stock equivalents. Diluted EPS is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period plus the weighted average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method. For periods with a net loss, the dilutive common stock equivalents are excluded from the diluted EPS calculation. For purposes of this calculation, common stock subject to repurchase by the Company and options are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive.
Stock Compensation	Stock Compensation
	The Company accounts for all stock-based payment awards made to employees and directors based on their fair values and recognized as compensation expense over the vesting period using the straight-line method over the requisite service period for each award as required by FASB ASC Topic No. 718, Compensation-Stock Compensation. Restricted stock is valued using the closing stock price on the date of the grant. Options are valued using a Black-Scholes valuation model.
Fair Value of Financial Instruments	Fair Value of Financial Instruments
	The Company measures and discloses fair value measurements as required by FASB ASC Topic No. 820, Fair Value Measurements and Disclosures.
	The carrying value of accounts receivable, foreign cash accounts, prepaid expenses, other current assets, accounts payable, and accrued expenses are considered to be representative of their respective fair values because of the short-term nature of those instruments.
	Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, the FASB establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:
		•	Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
		•	Level 2 - Include other inputs that are directly or indirectly observable in the marketplace.
		•	Level 3 - Unobservable inputs which are supported by little or no market activity.
	The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
	As required by FASB ASC Topic No. 820, we measure our cash equivalents and short-term investments at fair value. Our cash equivalents and short-term investments are classified within Level 1 by using quoted market prices utilizing market observable inputs.
	As required by FASB ASC Topic No. 825, Financial Instruments, an entity can choose to measure at fair value many financial instruments and certain other items that are not currently required to be measured at fair value. Subsequent changes in fair value for designated items are required to be reported in earnings in the current period. This Topic also establishes presentation and disclosure requirements for similar types of assets and liabilities measured at fair value. As permitted, the Company has elected not to use the fair value option to measure our available-for-sale securities under this Topic and will continue to report as required by FASB ASC Topic No. 320, Investments-Debt and Equity Securities. We have made this election because the nature of our financial assets and liabilities are not of such complexity that they would benefit from a change in valuation to fair value.
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash and cash equivalents generally consist of cash, government securities, mutual funds, and money market funds. These securities are primarily held in two financial institutions and are uninsured except for the minimum Federal Deposit Insurance Corporation (“FDIC”) coverage, and have original maturity dates of three months or less. As of March 31, 2015 and December 31, 2014, bank balances totaling approximately $9.7 million and $9.9 million, respectively, were uninsured.
Short-Term Investments	Short-Term Investments
	Short-term investments consist of U.S. government agency and government sponsored enterprise obligations. The Company accounts for these short-term investments as required by FASB ASC Topic No. 320, Investments-Debt and Equity Securities. These debt and equity securities are not classified as either held-to-maturity securities or trading securities. As such, they are classified as available-for-sale securities. Available-for-sale securities are recorded at fair value, with unrealized gains or losses recorded as a separate component of accumulated other comprehensive income in stockholders’ equity until realized.
Accounts Receivable	Accounts Receivable
	The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company maintains reserves for estimated credit losses, and those losses have been within management’s estimates. Allowances for product returns are included in other adjustments to accounts receivable on the accompanying consolidated balance sheets. Product returns are estimated based on historical experience and management estimations.
Equipment and Improvements	Equipment and Improvements
	Equipment and improvements are stated at cost. Depreciation is computed using the straight-line method based on the estimated useful lives of the assets, generally ranging from three to seven years. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life of the asset or the lease term.
Segment Reporting	Public companies are required to report financial and descriptive information about their reportable operating segments as required by FASB ASC Topic No. 280, Segment Reporting. The Company has two primary business units based on how management internally evaluates separate financial information, business activities and management responsibility. Wireless includes our QuickLink®, NetWise® and CommSuite® family of products. Productivity & Graphics includes our consumer-based products: Poser®, Anime Studio®, Manga Studio®, MotionArtist® and StuffIt®.
Income Taxes	We account for income taxes as required by FASB ASC Topic No. 740, Income Taxes. This Topic clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Topic also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Topic requires an entity to recognize the financial statement impact of a tax position when it is more likely than not that the position will be sustained upon examination. The amount recognized is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. In addition, the Topic permits an entity to recognize interest and penalties related to tax uncertainties either as income tax expense or operating expenses. The Company has chosen to recognize interest and penalties related to tax uncertainties as income tax expense.
