wxPython before MainLoop

I'm disappointed that I didn't get a wxPython solution.

If the only way to get wxPython to correctly handle
this simple task is to code around it, I don't think
wxPython is really ready for Windows.

Is there a better place to ask?

Regarding the suggestions:

Bjoern, you're wrong. The GUI needs to be displayed
for the user to analyse. A delay between display and
readiness is much better than a delay before display
or a delay with the GUI half-drawn.

Mike, the screen does display correctly, it's just
that in Windows, screen updates are not processed
while the application is busy.

7Stud, that's a solution. Unless anyone comes up
with a direct solution, I guess I'll have to do that.
