Sorry for any misunderstanding, but as i wrote in my first posting it's all about a background
picture (not color) here
I have set the background color as white, no problem with that.
But i'd like to be able to choose "no background picture", i don't need any. Or if i
have to choose anything than i'd like it to be as near as possible to nothing, which is "white". But there is no white.
