As a test, you should try to make a minimal reproducing example without Twisted (e.g. just launching a new thread instead of using thread pool). My guess is that this is something to do with COM's threading rules (they're complex, apparently - the Python Win32 book has an appendix discussing the issues), or perhaps a bug in win32com. But that's just a guess, thus the need for a minimal example. _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
