If you have had a number of people connect and chat using the BibleBox you would have noticed that the chat messages end up overflowing across the form fields. An example is shown below:
I have modified the html and css for this and the updated files to replace structure.css, index.html and chat.html are available here.
I changed the code so that the Chat messages stay within the frame and a scrollbar appears once messages reach the limits of the frame.
