Vizard and Networking

[pattie]

Soryy if this is considered a stupid question. I am trying to run the duckwalk.py example on my network at home.
I am using 2 computers with the Beta2 version of Vizard installed on each of them.
When it asks for the machines names I enter them and it seems to connect correctly to those machines (each running windows XP Home).
I disabled every firewall or what I consider might be a source of problem.
So far, I have not been able to see the ducks move in the labyrinth.

Am I missing something?

Thanks
Patrick
