I'm using Empathy to join a Jabber chat room. I have this setup on two Ubuntu machines, both running 12.04. To the right of the chat window should be a list of all the users currently in the chat room, but on one of my machines this list isn't there. How can I get it to appear?
Closing/reopening the chat room or rebooting don't make any difference. There are no menu or configuration options that I can see to control whether or not this list is shown.
