Wondering if anyone can help wth this. On Windows XP I had a photo from My Pictures set as a desktop background. Now screen is blue after turning on and I cannot save anything in My Pictures as a desktop background. When I go into the desktop properties and go to Themes I can click on any of the themes but nothing changes after clicking on Apply. When I go into backgrounds I can no longer use the drop down box to choose a background as it is unhighlited. When I shutdown XP the image that I originally had on the desktop appears briefly befor the computer turns off. Any problem solving techniques for this would be greatly appreciated.
