Hi Mark,

I tried your attached program and didn't see the bad behavior you described.
I tried it with Twisted trunk at HEAD, Python 2.5.1, and wxPython  How does this compare to the versions you're using?

Differing behavior on different platforms doesn't surprise me at all, since
wx itself has a lot of subtle differences on different platforms.
