Robert,
It is osgviewer, the latest CVS version.
OK, that lest osgProducer/Producer and Don off the hook. And puts me on it :-)
I have a stack trace for the exit hang on OS X/X11. The osgViewer
receives an X error when I press <Esc> and then hangs in _XLockDisplay:
Got an X11ErrorHandling call display=0x180a800 event=0xbfffe460
^C
Program received signal SIGINT, Interrupt.

Any Ideas?
No ideas right now, so will need to expand on what the set up is.
Could you explain what system(s) you have seen this problem under.
Things like OS, hardware are all important. You mentioned one machine
on osg-submssions, is this the only one? Reinterating the
configuration here on osg-users will help others get any idea of where
the problem is occuring.
Is the osgviewer running multi-threaded, multi-screen? Do you know
which threading model its chosen? I'll add text label to the stats to
report this. If you press 'm' the thread model is adjusted, the new
threading model being printed to the console. It'd be interesting to
see if some threading models have the problem, other note.
If you are running across two screens try:
osgviewer --screen 0 cow.osg
Then see if the problem on exit occurs.
Where the trail might lead I don't know, it could be an GLX bug under
OSX, it could be an osgViewer::GraphicsWindowX11 bug that isn't
revealed under Linux, it could be a threading problem.
Robert.
