Line Of Credit [Abstract]
Line Of Credit	4. Line of Credit On July 9, 2004, the Company entered into a line of credit agreement with JPMorgan Chase, N.A. (the "Chase Line") which, as amended, permitted the Company to borrow an amount equal to 80% of the book value of all eligible accounts receivable plus 45% of the value of all eligible open renewal orders (provided the renewal rate was at least 85%) minus $75,000, up to $2,000,000. The agreement bore interest at 1% per annum above the prime rate plus an additional 3%, at the bank's option, upon the occurrence of any default under the note. The interest rate was subject to a floor equal to the sum of (i) 2.5%; plus (ii) the quotient of: (a) the one month LIBOR rate divided by (b) one minus the maximum aggregate reserve requirement imposed under Regulation D of the Board of Governors of the Federal Reserve System. The agreement included a non-usage fee of 0.25% per annum on any unused portion of the line of credit and was secured by substantially all of the Company's assets. The line of credit limited repurchases of common stock, the payment of dividends, liens on assets and new indebtedness. It also contained a financial covenant requiring the Company to maintain a minimum debt service coverage ratio of 1.2 to 1.0. The Chase Line was terminated effective July 27, 2011. On July 27, 2011, the Company entered into a Loan and Security Agreement (the "Agreement") with Fifth Third Bank ("Fifth Third"). Pursuant to the terms of the Agreement, Fifth Third extended to the Company credit facilities consisting of a $1,500,000 revolving credit facility (the "Revolving Loan") and a $5,000,000 term loan facility (the "Term Loan" and, together with the Revolving Loan, the "Credit Facilities"), which matures on July 27, 2014. Each of the credit facilities bears interest at a rate based on the one, two, three or six month LIBOR (as selected by the Company on the last business day of each month) plus 4.0% (effective rate of 4.30% as of January 31, 2012). There was $0 outstanding and $1,500,000 available on the Revolving Loan as of January 31, 2012. The Agreement contains covenants that restrict, among other things and subject to certain conditions, the ability of the Company to incur new debt, create liens on its assets, make certain investments, enter into merger transactions, issue capital securities (other than employee and director options, employee benefit plans, and other compensation programs), and make distributions to its shareholders. Financial covenants include a minimum fixed charge coverage ratio, as defined in the Agreement, of 1.2, and a senior leverage (maximum senior funded indebtedness to EBITDA) ratio, as defined in the Agreement, of 2.0. The Agreement also contains customary events of default which, if triggered, could result in an acceleration of the Company's obligations under the Agreement. The Credit Facilities are secured by a first priority security interest in substantially all assets of the Company and by a first priority pledge of all outstanding equity securities of each of the Company's domestic subsidiaries and 65% of outstanding equity securities of the Company's foreign subsidiaries. The Company was in compliance with all debt covenants as of January 31, 2012.
