fair enough.

see the references I gave earlier if you want to bother with that.

fair enough.. what did you have before? but this should do it:

    def OnClose(self,Event):
        self.Destroy()

that will destroy the Frame, which should make wx exit.

If you don't do that, you may need to call

OnClose
    Event.Skip()

to make sure that the Close event keeps going and does its thing. If
you had a handler for it, and did not either Destroy the frame or
callSkip(), ,that might explain the behavior you saw.

Anyway, I've never needed to explicitly end the MainLoop.
