Let's see if I can duplicate what I saw yesterday on my own board (somehow I'm doubtful I can).

First I put up some text, several line returns, and a few bold statements:

Test blah blal blah

blah blah blah blah


blah blah blah blha

Then I attach 3 images. Then I edit the post. Then edit it again to delete an attachment, and add a newer version of the corrected image.

At that point, on my board....all the field text in the editor went a little whacky.. showing the text all run together with the code tags visible.

EDIT: And of course I'm unable to duplicate the error here. Naturally. Go figure.
