I am sorry, but I must say there must be some compatibility problem with new WP. My test environment is:
- default theme Twenty Eleven 1.2
- all other plugins deactivated (yes, TinyMCEAdvanced also deactivated)
The result is that TinyMCE visual editor panel has completely disappeared. It is same result both for the FF6+ and Chrome. IE8: panel is still visible, but no "TinyMCE-span" could be seen.
Perhaps it would not be difficult to fix it for you.
It will be really VERY useful plugin!
With best regards, Joo
