It's very strange but it works perfect when I rename python.exe into
something else and run with it.

Has it something to do with previous versions installed? I had
Python2.3bx and 2.3c1 installed on this machine and didn't uninstall
them before I installed Python 2.3.2.

Why does this happen? How can I solve this problem?
