Client Server Networking Problem

Vizard serializes the arguments to a string and sends that to the remote computer. To serialize the data, Vizard uses the cPickle library that comes with Python. Perhaps you are trying to send an object that cPickle does not recognize.

It's difficult to tell without having a simple example that reproduces the error. For help with code on the forum it's always best to follow the posting Vizard code guidelines.
