Problem with 3.0 Install on Windows

[Saul Spatz]

I'm running python 2.5.x on Windows XP, and I installed 3.0, just to get 
familiar with it.  I have a directory with all my python projects in my 
PYTHONPATH variable.  When I try to run python 3.0, it detects a syntax 
error (a print statement) in the first file in this directory, and 
crashes.  I don't want to convert the files to 3.0 syntax, because I 
plan to keep using 2.5, at least for a while.

I don't know exactly why this translation is happening.  Is there a way 
to turn it off?

Thanks
