Diez, Scott, and Bruno, I thank you all for your help and suggestions. I wasn't aware that default values were considered class (static) values. That seems a little odd to me, but as long as I know that's the case, I'll be fine.
I initialized my list member in the __init__() method and all is working as it should now. Again, I thank you all. -- http://mail.python.org/mailman/listinfo/python-list
