[Tutor] wxPython window flashes open and closed

I had the same problem. You need to redirect stdout/stderr to a file.
By default it goes to a console window, but this disappears
immediately after the program exits. So if you've got a fatal error
that causes your program to die before it gets started, well, you'll
never see it.

This message describes the problem and the solution. Worked for me.
