Paul, it sounds like she doesn't have a rate statement in her animation 
loop and is running VPython 6 whereas you're running VPython 5.

I've never seen before. She has an animation program that works. It 
creates objects, updates positions and such. However, the animation window 
itself is a featureless light gray box until the program is complete. Then 
the final state of the objects appears.
