If I make a post with an attachment added, then go back and edit that post (specifically to add a caption to the attachment) I get this in Fx and Chromium. Note the red box area, no way to add or edit the caption.
If I do the same thing in IE9, I get this box, which lets me edit the caption.
Someone tried the same thing on a Mac with Safari and there was NO edit for the caption either.
A site bug or something else?--
