O:\local>python test_qt.py

Could you elaborate on this briefly?
I have Visual Studio 2008 installed for C++ development. However, I do not understand how this works with python.

I should have mentioned that this one is from another workstation (same version/configuration).
Additionally: Resizing the companion window makes it crash:
