Screen Saver May Not Start in Windows XP
http://support.microsoft.com/default...b;en-us;326719

Posting from another user by the name of David:
”I figured out what the problem is. It's the Microsoft Wireless Mouse. If I switch
the mouse to one with a tail the screensaver works.”
then David posted again
”I got a fix. I changed to connection to the computer using the USB to PS2 adapter
that came with the mouse. Now I get the screensaver. I would be interested to find
out why this works.”
