Such a change should not cause the entire client to fail. Can you try
running the VenueClient from the command line and see what you get?
cd \program files\agtk-3\bin
venueclient3.py

Hi Thomas,
A fuller account of the symptoms.
The machine was not displaying any incoming video streams. A problem noticed
on a few other older dell optiplex machines. I shut down the venue client and
copied the patch processmanager.py file (see attached) as the routine procedure
when seeing that problem. The client does not launch anymore at all. :-s

Hi Nic:
The only problem I see is a failure to connect to the Jabber text service
at one time last week, when there was a problem with the server, and
an error using the AGSC bridge.
Did you encounter some other problem?

We are experiencing a problem launching the AG client on a winxp sp2 box.
see attached logs.
Any ideas?
