[wxPython] newbie question/problem

I am using Pythonwin as my development environment. I’ve noticed that as soon as I hook up any event handlers I have to re-start my development environment each time I run or debug from within Pythonwin otherwise I get an “Application Error”. This does not occur if I don’t make any calls to EVT_SIZE, EVT_MOVE, EVT_MENU etc.

Any ideas on what I might be doing wrong?

Chuck
