Geesh.. I think it's you who has the attitude. I said what the settings were under XP, and you said:

"This means that changing the color of the item "Window" in the Appearance tab of Display Properties will not change that white background to something else.

I didn't have an attitude, I just stated that I had in fact tested it out and not pulled it from somewhere. If having an attitude is stating that what I posted was factual then sorry I tried to help out. If I should have simply made guesses first, and then complained when someone pointed out my error, I stand corrected.
