I obviously overcomplicated that, so to restate the problem:
In Windows XP, minimizing/restoring
any Pygame window several times in quick succession by repeatedly clicking its icon in the taskbar causes a Pygame error and crash.
This happens even on a brand new install of XP, as long as animated minimizing/maximizing is disabled (System Properties->Advanced->Performance->Custom->Uncheck first option). It often takes a few abort-and-retries to get a crash however; after some experimentation, getting crashes seems much easier when some
custom msstyle theme is installed, which causes Windows to not always properly obey taskbar-given minimize commands, which Pygame doesn't like at all.
I haven't
been able to test this on Vista or Windows 7 yet, but does anyone know anything about this rather bizarre problem?
