Ok, I can try that.

The bad thing is that mouse motion stops at the edges of the screen.  I
already tested XWarpPointer to bring it back to the center when
necessary which works somehow.  But this breaks when a button is
pressed, then I do not get more motion/leave events.  What can this be?

And, by the way, what is the XWarpPointer analogon on Windows?
