Hi Robert,
You mention that the problem is hanging somewhere in the new texture object
management code; I have seen osgcatch hang on exit before your new object
management code was added.
This leads me to believe that either the two issues are separate, or they are
both related to the same thing. Unfortunately I was not running the debug
version of osgcatch when it did hang, and it very rarely happened to me (maybe
twice out of about fifty times running osgcatch). I still haven't been able to
get it to hang on-exit using the newest svn revision.
Just a few more issues I wanted to bring up regarding osgcatch: Sometimes I get
a crash mid-game with the error "List iterator not incrementable". Further
debugging leads me to the GameEventHandler::handle() function where it attempts
to move objects
for(CatchableObjectList::iterator itr=_catchableObjects.begin();
itr!=_catchableObjects.end();
++itr)
{
}
(here's the stack trace if anyone's interested)

where it strangely attempts to increment past the end, leading me to believe an
iterator is being invalidated somewhere.
The particle effects are strangely also not working for me, they all appear in
the bottom left corner of osgcatch where the blue background and sky texture
meet.
I'm running on Windows Vista 64-bit with an NVIDIA card with the latest drivers.
Sorry for not being able to get to the cause of the problem -- but hope I've
provided some insight.
Regards,
Kim.
