Sometimes during shutdown on my XP SP2, I get a pop up box claiming that a program "sw.exe" will not shutdown because it is waiting a reply from me. I then end it and shutdow. I have searched the computer for "sw.exe", scanned the msconfig set ups, searched the files in task master, and searched the registry; all to no avail trying to find who or what is generating this messsage. Can anyone out there tell me a method to find out what program is causing this pop up box to be generated?
