well, it works because wxPython drops exceptions in event handlers. But the
"right" thing to do is to check if the Window has the mouse Captured first:
if self.Canvas.HasCapture():
self.Canvas.ReleaseMouse()
kind of klunky. it might be worth writing a little method:
ReleaseIfCaptured()
or something....
