Thank you, I mis-read the docs. The mistake I made was having was using a weak reference as a key in the dictionary. Weak references will be very useful for me. I really enjoy python. So many good things have been added to the language without taking the fun away :-) Mike -- The greatest performance improvement occurs on the transition of from the non-working state to the working state. -- http://mail.python.org/mailman/listinfo/python-list
