I'm using windows XP and recently installed a second monitor. Now everytime I come back to my computer after being locked the wallpaper that I set is being reset to the default background. When I go to display properties though, it has the picture selected. I also tried putting the image into the web folder, checked to see if the desktop was locked under customize desktop in the display properties, and did a virus scan. I can't see any reason why this is being reset.
