SOSAD - it's a technical glitch that happens when a user includes an unusually long URL. MyAmerica included a long URL which I then cut out and replaced with a TinyUrl substitute. The long URL presents a problem in that if allowed to exist 'as-is', will force the HTML table object to automatically size (expand) in the horizontal (toward the right) of the page. You can manually 'break' (line-wrap) the URL but then a user has to reconstruct in manually.
As a courtesy, I just do a TinyUrl replacement when this type of situation occurs.
Check it out (it's free and easy to use!):
