This just started tonight. I'm running XP Whenever I open and then close Windows Explorer, Control Panel, and several other windows, as soon as I close them the desktop goes blank and then they come back. It's almost like it's resetting itself. Sometimes the "restore active desktop comes up and I have to say ....restore. I have checked everything, I have run a reg cleaner, several spyware programs......ran win doctor, and disk doctor......I have rebooted several times. Nothing came up with anything. I have not added, installed, or downloaded anything today and it was fine today and all of a sudden tonight it started doing this.
