I know that with Vista Ultimate RTM x86, if you have a Microsoft Wireless
Laser Mouse 6000 (amongst others, I believe), the screen saver won't
activate under current Microsoft mouse drivers. But, I don't know if that
applies to x64 or why this would happen all of a sudden on your system. No
driver updates or scheduled task changes?
