The screen isn't redrawn, a simplified scene is rendered off screen to detect 
what was clicked.  That being said it does use the same display list for the 
pieces, a slightly less accurate "piece" could be drawn which would be quicker, 
the reason I didn't bother is because this off screen "drawing" is very quick.

The fact it occasionally takes a long time to do this is likely a problem with 
the graphics driver, but maybe there is something that could be done in the 
code.  It's difficult for me to try anything as I don't get the problem, maybe 
when I get a machine with Vista on it I might be able to reproduce it.

Seeing if replacing gtkglext with normal widgets is possible is next(ish) on my 
todo list...
