Robin,
Thank you for your help.
But how can I find out more details about the problem that caused shutdown?

That error just means that the app has shutdown uncleanly and that
there are still windows existing. Probably something failed in the
OnInit and the true traceback showed up only breifly in the stderr
window.

Sorry, I was going to add a comment about that but got sidetracked.

This has been discussed a few times and there are a few different ways to handle it. (And probably a few mentioned on the wiki too...) Basically you need to try and catch errors in the OnInit or your main frame's __init__ so you can do it with a try/except, or you can run the app with python -i so the interpreter doesn't exit when the app is done. Or you can give a filename to wxApp.__init__ so it will write stderr to a file, etc...
