Importing os has started failing on the Mac since the riscos mods are in there, it tries to use UserDict without having imported it first. I think that the problem is that the whole _Environ stuff should be inside the else part of the try/except, but I'm not sure I fully understand what goes on. Could whoever did these mods have a look? Also, it seems that the whole if name != "riscos" is a bit of a hack... -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen@oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | ++++ see http://www.xs4all.nl/~tank/ ++++
