I noticed the same thing on a Vista box. After a while I noticed that the mouse pointer was moving a pixel (or a couple of pixels) in a circle if the mouse pointer was in the upper left-hand corner of the screen. It moved automagically every 30 seconds or so.

I go in, reset it to 10 minutes... reboot and once again the Wait Time is back to 1 minute.... go figure... This was this way from the very first, upon setting up the PC but before adding any NEW 3rd party software that did not come pre-installed.
