I'll look for that. I do remember a few days ago syncing my install withthe SVN, and removing a TinyMCE theme folder "zenphoto", thinking it was old and unused. It's not in the nightly builds or svn, so if those were required files, they probably should be, no?
I put 'em back from the 1.3 install, but still no good. Interestingly, if I click "toggle editor" to go to plain text, then toggle again back to TinyMCE, it shows up as expected.
