Problem with wxPython: wxDialog crashes inside PythonWin

I'm getting some strange behavior from wxPython. It happens only inside
PithonWin, when I try to open a wxDialog. The problem is always
reproducible if I do the following:
- Open the script inside PythonWin
- Run it once, and open the About box Dialog as many times you want. It
- Exit the wxPython application
- Run it again, and try to open the about box.
Then I get this error (that's the brazilian versions of Windows, but you
should understand it)
PYTHONWIN causou uma falha de página inválida no
módulo PYTHON21.DLL em 0167:1e132ecd.

I got the problem first in a script of mine, but I could reproduce it using
the script that's given in the tutorial on the wxPython website. I'm using
Python 2.1. Here's the version string. The script is at the end of the email.
PythonWin 2.1 (#15, Apr 23 2001, 18:00:35) [MSC 32 bit (Intel)] on win32.

Other related things:
- The error window shown above has a close button, but the application
keeps stuck. I need to Ctrl-Alt-Del, and then ask Windows to finalize the
wxPython test application.
- Sometimes I can call PythonWin again right after the bug happens. The
machine seems to be stable, no other problems happens for any other
program. But sometimes PythonWin takes ages to reload after this problem.
I'm stuck with this one (that's my first wxPython project). I think it is
related to some kind of conflict between PythonWin and wxPython. Can
someone help me?
