;-) We'll see ;-) It's certainly a goal to aim for. (to aim at?)

Err.. actually I use a non-resizeable window and it works great too. Well, I
want to make the window scalable with const aspect ratio anyway.

Well, and then the Winmanager catches the Window, but the server sees a closed 
connection and exits. So apart from the few frames which get displayed in a 
seperate window, I can live with it, or do miss something?

That's what I did ;)

Yeah, works great.
