Hi Paul,

I have just tried your modified osgprerender and can confirm that
problems exists on my system as well.  I don't the cause of the
problem, my best guess right now would be something like inappropriate
reuse of GL objects.

Robert.

These changes simple "recreate" the viewer after hitting the escape key rather than simply exiting the executable. These errors (constantly displayed) started showing up once the viewer is displayed the second time:
