I'd bet money on this having been addressed here before, but I can't find it. After I installed updated Systemworks, the system is hanging at the welcome screen. ctrl+alt+del gets me to the desktop and I have no more problems. Once in a while, but not always, I get the "virtual memory low" message over the welcome screen; when i exit from that, XP pops into the desktop with no problems and certainly no memory issues. Any ideas?
