Wolfgang,
I have seen your question often in this newsgroup, in my opinion did I not
see a real fine answer.
Or you should draw using the region class your own window.

(And don't ask than here how to do it, you can probably than better search
for it on Google, it is such a lot of work measuring all points on the
screen that you need for that. And therefore it is in my opinion almost
impossible to help with that directly in a newsgroup)
I hope this helps a little bit.
