--- Comment #2 from Roderick Colenbrander thunderbird2k@gmx.net 2008-03-11 06:06:28 --- I have tested it here on a Geforce 7600GS. I don't have experience with the program but it appears to work fine using a sample model file. Nothing renders outside of the window. For opengl/direct3d 'child window rendering' (3d views) we use an AIGLX-like mechanism and not all drivers support this properly yet as it is quite new. If a driver doesn't support it, weird things like this could happen.
