It's a new one on me, Pat (so Thomas may be right!) Can you tell us a little more about what you may have done, and what you mean by a background picture all the time? (What picture?)
It was weird. The titles all had a background picture, scamp 16, so I could barely read the text. The new messages side bar had the background and the forums. It is fine now. Back to white. Maybe it was an iPad glitch.
