"Your topic is similar to..." blocks comment pane

I just started a new topic in SFBA, and the system presented a pop-up with the message
in the topic header. The blue pop-up covers the right half of the comment box, so I have to put
hard carriage-returns on each line. I don’t see a cancel button, even when I make my browser
full-screen.

And it happened just now as I’m typing. Screenshot:

Fixed. thanks.
