While we are waiting for the new version of the chat to arrive, I thought I'd let everyone know this cool trick I found by accident.
Sometimes when the chat freezes, you can jump start it using the following technique:
1. Press the browser Reload/Refresh button
2. Immediately after, press the Stop button (so that the page doesn't have time to reload)
3. Wait for a few seconds
4. Chat starts moving again
I have now been using this technique in chat for about 7 days, and it hasn't let me down once. Of course it's not the perfect solution, but it should help out with some of the frustration. It probably won't work with all the browsers, but try it out.
