I have begun having an occassional problem.. Been on Windows 7 for a few months now, and a problem JUST started happening in the last week or so. Every now & then, my desktop is completely black, no wallpaper, no icons, nothing. I have my taskbar, and any programs show up fine.. I can even right click on the desktop & the right click menu comes up fine. I can hit the show desktop button & everything pops up fine, but as soon as I open any other window, the desktop is gone again.. wallpaper & all. Does anyone have a clue about this?
