Problem 2 (windowed):
We are using gnome on Ubuntu, and
osgviewer --window 100 100 500 500 cow.osg
works fine, but after 'f' is pressed two times (first into fullscreen, and
then back to windows), we dont get a window.
So it seems that it is not possible to go back from fullscreen windowed
Problem1: Yes, It seems to be a bug for windows only, so the problem is
probably as you say in GraphicsWindowWin32.
