I am trying to start a meeting, but only one person is getting the meeting console pop up. I am just getting a message that i should join, but when i click on join nothing happens. I tried it with several other users, but when they click on join nothing happens. The only thing i am able to do with everyone is chat. I restarted the Sametime server, but same behaviour.
I am wondering if there is any plug-in that i need to have installed on the machines that are not responding.
