I had the same problem as the first post, but then I realized that it was Js interference. For me, the trouble plugin was Slideshow Gallery Pro, but it could be any plugin that uses JS, or possibly even the theme. My suggestion is to turn off all plugins and see if it goes away, if yes, then turn them all on one at a time till you find the problem. If not, try switching to 2010 theme with plugins still off, and if it works, try turning all plugins on one at a time.

Cela: I had the same problem. Because the visual mode isn’t loading, it’s not creating a slug for your post until you switch to html mode.

Johansensen: I can’t say for sure what the problem is since you’ve already tried what fixed my problem, but I would suggest downloading an older version of wordpress and copying the tinymyce files from it in place of your tinymyce files. (back up and delete the old ones before you do. Otherwise you may still have a bad js file in your install.)

Peoney: TinyMCE is a program that works hand in hand with wordpress to give you the editor that displays images instead of raw code… among other niceties. It’s installed inside wordpress, but it’s developed by an outside team.
