I've always had My Documents on its own drive/partition. Favourites (not used), My Music, My Videos and My Pictures. Yesterday, I went to change a background, and lo and behold, rundll32.exe would hang (Display Properties/Desktop Tab). And only, this tab. Not only that, I'd lost the ability to right click an image and select Set as Background, it simply wasn't there. ??? I'd installed a new game (Chaos Theory), didn't make sense that a game would do that, right? Still, out it came, no change. Still couldn't change the background. I restored my original image (all updates - at the time, and all drivers). All was well. Okay then, reinstall here we come. All drivers and SP2 (slipped) - forgot the updates. No problem. Tab was accessible. Install all the updates. I change the location, and boom, Desktop Tab would hang. I revert to the image, bingo, no problem. I install Powertoys, change the My Pictures location, boom... tab inaccessible. I move the folder back to its default location, bingo.. tab would work. I move it manually (via regedit), tab wouldn't work. I revert, no problem. ??? Ideas? Resolved A freakin' jpg!!! No a virus, nor a trojan... a worm or malware. A bloody jpg. Grrr
