I'm very careful in my code to ensure all acttors are checked before any windows are destroyed and also, when an actor is removed from a window, that it needs to call release graphics resources too.

Yes, I have the same problem in java with ReleaseGraphicsResources 
getting called when the RenderWindow is freed - you need to be sure that 
all the actors are cleaned up first though, or really bad things can 
happen.  I'm not sure if this is a design problem or a bug.  Any 
comments from someone at vtk?
