Hmmm, the next time I will boot in Win2K, I will try to have a program
continously print the content of the ClipCursor while another one changes
the resolution just to check what happens :-) This way we will be sure
exactly what Windows does.

If it really propagates, we will see when we will merge both patches :-)
