Thanks for that info, it could potentially make my life a lot easier
<wink>. Looking over my emails again it seems the problem was with
Python built with VC7 and extensions built with VC6. Martin von Loewis
and Thomas Heller both reported crashes in this scenario. Tim Peters is
also intimately involved with this issue, so if anyone has any insight
it might be worth it to report it to PythonDev...
