How to use "chat"?

I an having trouble using "chat in "live chess".

I click on "chat", then on "join" and nothing happens. (I must be dense.)

According to the tutorial, ...

How to Chat - To chat in simply type into the white text box below the chat area and hit ENTER on your keyboard.

Hello again,

There is no white box below the chat area.

Thanks

When I launch Live Chess, I see something like this ...

The ALERTS tab is active. There is one line for typing input. Do you get something different in Live Chess?

If I then select the CHAT tab, I'm presented with a list of chat ROOMS that I can JOIN. Having JOINed, I see a one-line text-entry box, similar to the one in the main chat area.

Any chance of you posting a screenshot of what you see?

I have succeeded in getting "chat" by using the "detach" button. Thanks to those who posted to this question.
