Help with wxPython program :.: return 1?

[Kenny x]

Hello, I have a problem with my wxPython 2.8 Application.
The program opens and closes and on KomodoEdit it says "wxstreamredirect.py
returned 1.'
 What's wrong?

P.S. I compared my source code to the source code in wxPython in Action,
and it looks the same! Why does my program open, then return 1 and close?

Any help Appreciated! :)
