How do you know what my next Question would have been?

Thanks for this tip!
I've had an 1040 ST with that monochrom monitor. I think that's the reason why I dont know about wallpaper stuff.
As far as I read, Thing Desktop is one of the most modern Atari desktops. Is that true for today?

Thanks for reply too.
I'll try it with ImageCopy first.
Where can I find the current devel version of XaAES? Do you mean these:
