No worries Todd, it is alpha. It was a very recent bug in the 8.10 ia32-libs package, which is now fixed :-D Thanks for the excellent writeup, BTW! I've been wondering what was involved in doing this for a while, it just never made it up my priority list to figure out. Again, thanks! -- http://mail.python.org/mailman/listinfo/python-list
