Python 3.3 Permission Error with User Library on Windows

I have certain scripts that run without error on Python 2.7 and 3.2. With Python 3.3 they get a "Permission Error". This does not occur with every script. The difference seems to be that the ones with a problem use a local user library. The ones without a local library are OK.

A test case is attached. Do not change the directory names. Double click on the file run_test.bat to run. You may need to change the path to the Python executable on your computer. It runs the script astyle_protected.py which uses the library libastyle.py. It runs OK with Python 2.7 and 3.2. But gets an exception with Python 3.3.
