[Visualpython-users] CPU usage

If I run a python program that uses vpython to make a scene and then  
leave the scene sitting open (no looping going on), I find that python  
ends up consuming 30-50% of my CPU cycles.  Is this normal?  If  
something were happening, I wouldn't be so surprised, but all that  
should be happening is the default checks to see if I interacted with  
the window in any way (rotating or zooming).
