On chat, all of a sudden, the messages others are typing stop showing.
Sometimes this happens only in 1-2 private chat windows; sometimes in all windows, including the main chat.
The only way I realize this, is when I realize all I see is myself typing, as if I'm chatting with myself.
However others are able to receive and see what I type.

On looking at chat history, I am able to see what others have been saying.

Using Mac OsX. I use Google Chrome, Safari or Opera usually. Have the same issue on all browsers.

I believe others have similar complaints. And it has been reported earlier by others.
