Starting a thread before wxPython bootup ... interesting.

[david]

Since the observed behaviour is clearly undefined,
I forgive you for the poorly specified behaviour
description: asking for a close description of random
behaviour is just ridiculous.

The most obvious point is that wx is not re-entrant
or thread safe: you have to make it so by using
wx.CallAfter()

Since you are talking about a bug in your screen
display while using a screen library, it would
also be interesting it you described the environment:
Which operating system? Which windowing system?
Which wx library? Which Python? Which IDE? What code?
