I already noticed that enter events moving mouse can be *really*
annoying, when trying to top Hatari window that's mostly covered
by another window.  It can result in enter event always moving mouse
from Hatari window to the overlapping window, if Atari mouse
location within Hatari window happens to be below the overlapping
window...

Does somebody like that feature enough that it makes sense improve it?
