hi there, a weird thing happened today... when i turned on my laptop i noticed my regular "bliss" desktop background has disappeared, replaced by a flat gray background. i checked out my display options in the control panel, and i somehow appear to be locked out from my list of backgrounds. the word "background" above the list is in white and the list of backgrounds is grayed-in. the backgrounds are all still listed there, but none of them may be clicked on. the scroll bar in the backgrounds list is also functionally "dead". the only thing i can select and change in display options>desktop is "color", of which gray had been selected somehow. does anyone have any ideas of what on earth could have happened here and how i can get my regular background back? i am worried this could be a virus or something but ad-aware came up empty. thanks!
