Running an Intel (R) Core(TM)2 Quad CPU with 8 Gigs RAM and NVIDIA GeForce GTX 280 on Windows 7 (Upgrade from Vista Home). No video card problems, however for some reason desktop background is stuck on one picture (set for slide display) and Gadgets display has disappeared. Changes to Personalization do not work, nor does clicking "Next desktop background". No changes made to computer other than auto upgrades installed by Microsoft. Any solutions? I'm really tired of looking at the same desktop background day in and day out!
