In one of my experiments I got a crash in the destuctor of Viewer... My class was derived (indirectly) from both osgViewer and GraphicsWindow (multiple inheritance). I had to pass 'this' in the viewer's constructor to the function that sets the graphic context... I think that the instance gets deleted twice because of the ref_ptr stuff...
That's why I ended with two classes: my GraphicsWindow is now a member of my Viewer... seems to work: the metallic cow spins at 400 frames/sec on my laptop :-) @Raymond: I'll send you the sources monday, when I will be at my office again Goed Weekend, Hans.
