     This fourth  prospectus  supplement  supplements  and amends the prospectus
dated May 4, 1999, relating to 1,149,000 shares of our common stock, that may be
offered and sold from time to time by certain of our stockholders.

     Our common stock is traded on the Nasdaq  National  Market under the symbol
"FORG." On July 18, 2001,  the closing  price for our common stock on the Nasdaq
National Market was $1.25.

     On May 30, 2001, we announced our plan to conduct  business  under the name
"Forgent Corporation," and plan to change our company's name at our next meeting
of stockholders, subject to stockholder approval.

     We will  receive  none of the  proceeds  from the sale of the common  stock
offered by the selling  stockholders.  We will pay for expenses of preparing and
filing the  registration  statement,  the  prospectus,  this  fourth  prospectus
supplement and all other prospectus  supplements.  The selling stockholders will
pay all selling and other expenses that they incur.

     The   prospectus,   together  with  this  fourth   prospectus   supplement,
constitutes  the  prospectus  required to be  delivered  by Section  5(b) of the
Securities  Act with respect to offers and sales of the shares of common  stock.
All references in the prospectus to "this prospectus" are hereby amended to read
