[Ironpython-users] importing third-party modules

I recognized some strange behaviour. I've zipped the lib-folder of the  
IronPython-directory and loaded it with the script-tag as in the tutorial.  
That works fine, but I am just able to access the files on the first level.

E.g. open("lib/base64.py") works, open("lib/ctypes/util.py") fails. I even  
zipped the directory with two different programs (Windows-built-in and  
IZArc). Everytime the same behaviour.

Best regards
