wPython in Action: example chapter 1

[7stud]

Oh, yeah.  Not to mention: there is errata for the example.

I wonder: if the authors can't provide a simple, error free
introductory example, what chance to the rest of us have
of writing error free wxPython? 

I'm also fed up with running wxPython programs that briefly
flash the window at me and quit with no error messages.   
Is there some way to run wxPython programs where the errors
in the code are identified?
