I just wanted to let you know I had the same problem.  The editor for some reason just stopped working for me, and one of the items I tried to list had that happen.  I think I finally at least got rid of the blocks around everything by comparing the html code that was in a good listing (before the editor stopped working on my computer) and found some code that wasn't in the good listing and removed it. 

I'll be watching this thread to see if anyone can solve your problem and maybe it will solve mine.  I can't list anymore here until my editor problem somehow gets resolved. 

It would also help if you go to the Control Panel here on the forum page and set up a clickable link to your store so people can easily view it.
