It seems I spoke too soon.
I got it to work once and then, when I tried it again, it went right back to square one.
When I invite a guest, the invite window on the client comes sliding down and, after clicking on it, the chat window on the client opens up stating that I am connected.
Swicthing windows back to the opperator the chat window states that the connection to the chat server has been lost. The client window still shows "connected".
Approaching things from the other side (after closing both web page and operator app and restarting the whole system), I click on the live chat button (image) on the client side to initiate a conversation. The operator picks up the request and displays the status bar popup. I then accept the request and once again get the message that the connection to the chat server has been lost. The client side popup window plays it's alert tone and shows conected.
How now?
