Error running the demo

I got an error running the demo, trying the simple wxFileDialog.py example.

I am running Win32, Python 2.3.1, wxPython 2.4.2.4. And I do not have a E: drive (the debug statement below is coming from the wxWindow C++ implementation.)

Here's the debug tracing I got in the demo.

Unfortunately i did not notice right away it when it happened and it does nto reproduce easily. If i find a way to reproduce I will report it.

Cheers,
