My resolution is the same as it has always been from day one, but I did try changing the resolution which did nothing. The problems is affecting any wallpaper I apply. The wallpapers look fine when opened by any other prog. such as PSP, etc. I don't use DesktopX, IconX, Webshots or any other wallpaper program. The further I've come with this problem, the more I'm convinced it's not a WindowBlind problem. I had the W32IRC bot virus, got rid of it, but still have this problem with any wallpaper applied to my desktop. When I shut off my Windows Explorer, the wallpaper looks great, but of course I need that running. Is there a way to find out the dates of installed Window updates? I can try to uninstall the latest one to see if that solves the problem. I have Windows Explorer version 6.0.2900.2180.
