This also happens to me! However, I’ve never looked into it…

I just looked, and bbPress uses newlines to indicate breaks. This is parsed into <p>’s by a filter upon display. However, the edit textarea shows the unparsed text with just the newlines, and this gets mangled by tinymce.

If you set this tinymce config value, though, it will turn newlines into br’s, which should fix this problem for new posts:

I just tested this, and it works on new posts! (It won’t work on old posts…)
