Probably.  If I comment all the rendering code, then all the panels get 
the same number of OnPaint callbacks.  I was hoping that I would see the 
same number of refreshes in each window, though.

I knew this was probably an underlying window toolkit issue (outside of 
wx).  I was hoping someone might know a thing or two about the Windows' 
toolkit and could shed light on how it distributes the OnPaint events. 
I guess if I want them more even, I'll have to manage these updates 
myself and call Update() when all the windows need refreshing.
