User is on W2k Professional, using Web Client 9.150 connecting to Winnt TSE/Citrix XPe SP2. Whenever the user launches a published application, his local machine launches a printer installation wizard for a printer that used to be installed on the machine but is no longer. I tried removing his Citrix client (and the Citrix directory in Program Files) and re-installing it but the problem is still happening. I don't see anything on Citrix.com. Very weird.... - Bob Coffman
