Darn -- no I was hoping it was not platform specific. I think we could 
clean it up on Windows though -- but I only tested in on a Mac so far. 
Doing something with EVT_ERASE_BACKGROUND or something might fix it.

Well, yes and no. The newer versions of wxMac use CoreGraphics, which is 
a probably better drawing paradigm. It's what's causing these issues. 
However, In poking around the wxOverlay stuff (which I still don't get 
at all) -- there are comments referring to both wxMac and Windows XP -- 
so I think once everything is moved to the more modern interfaces, we'll 
be better off. But the transition is painful.

Any know of any more docs or examples for wxOverlay? The C++ headers are 
useless to me. -- have I know idea what methods it's supposed to have or 
anything.
