Not wanting to wait for a reply (in a hurry tonight, sorry) I just went ahead and changed the post as you said, and yeah, it must be the rich text editor breaking that, since I'm not having a problem with the HTML editor's result. I'd still like to see the mark-up behind what you're seeing, though - I don't use rich text so I would like to see if I can see what's breaking the end-result on your end.
Re: Maybe it doesn't work? Am I missing anything formatting-wise?
