What version of the AG toolkit are you using?

Some time ago, code was introduced in the VenueClient for the jabber  
component to reconnect to the server if it was disconnected for some  
reason. We previously had many disconnections like you - the  
VenueClient would continue to run normally but without any chat.  
However since that code was added, I can't remember the last time we  
had a complete disconnection problem like you describe. Of course that  
new code is no use if the jabber server itself is stuck, as happened  
today, but I don't think thats the cause of the more general problem  
you're describing.

Anyway, the question about toolkit version is really about whether you  
have a version recent enough to include the reconnection code.
