Hi, Ok. I'll take time to think about what's the best solution.

There is also a third solution, which is to reparent the glut window into whatever window ID you are given by the application.  There are a few things wrong with this method, for example, X events don't get to the application correctly in this case.  (I think there are workarounds, though.) dave... </blockquote></div>
