Checked for both Spyware and Virus, clean as a whistle. It only happens to some users, I set temporary files to just 1 meg and those get deleted when the user logs out of the server. Happens to the same users on all 4 citrix servers. Closes fine when I'm in there as admin. I have ran out of ideas on what it could be. Is there maybe a reg hack that will force IE to close if the last instance of it is closed?
Also, something of interest, I have disabled right clicking on the taskbar so users can't right click and then close the window (this works for me when I shadow them btw and it closes the instance of ie) However, there has to be something else going on, any ideas??
