[wxPython] pySketch and BOA constructor failure

Hi, I'm not sure why I am getting this error again.
wxPython and possibly python doesn't seem to be installed correctly, but I
don't what did wrong.
I am getting memory dump when I executed even pySketch.py and BOA.py. I
didn't do anything, just double-clicked them. I could use pySketch, but I
got the memory dump when I quit it. I couldn't see the BOA constructor. It
stopped throwing the memory dump.
I am using windows 2000 on Dell and ThinkPad machine. (I got the same
problem on both machines.) I am using the latest wxPython
(wxPython-2.3.2.1-Py22-hybrid.exe) and Python (2.2).

Is there anybody experience this problem?
How can I resolve this problem?
