In an effort to identify exactly which file is being used, I renamed the Level3Utils.py and Level3Utils.pyc files in the same folder as the script I'm working on.  The import command in PythonWin executed without error.  I looked for a file named Level3Utils.py in my Python tree (d:/Python25, in my case).  None were there.  I then commented out the import line and stepped through the code.  It ran without error!  The class that should have come from Level3Utils executed successfully without being imported!

 >>> import Level3Utils
 >>> Level3Utils.__file__
