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.

I'd like to refresh the display before I start the main loop.
I have code like this:
app = App()
app.Show()
app.long_slow_init()
app.MainLoop()
The main frame partly loads at Show, but because the mainloop has not
started yet, the display does not update until long_slow_init() finishes.
Alternatively, I could code
app = App()
app.long_slow_init()
app.Show()
app.MainLoop()
Which would give me a crisp Show, but there would be a long slow wait
before the app showed any activity at all. I would need a splash screen.
I'd rather not have a splash screen (and I don't know how anyway). I'd
like to just make app.Show() finish correctly before running
long_slow_init.
Is there a wx internal method that I can use to give Windows the
opportunity to finish painting the frame before I run long_slow_init()?
Or is there a better idea?

Chris is right. The only way to interact with a gui is with a separate
thread, otherwise you're blocking the gui's mainloop thread. That's
why I gave that link. That's how to do it in every GUI I'm aware of.
