All that shoes up are the words "HTML" and "Visual" and the buttons to insert images, media, etc.

I am using multisite and tried this in Firefox and IE 9 with all other plugins turned off. I also tried it using the twenty-eleven theme to make sure it was not a theme issue.... Additionally, I deleted my cached, reloaded, etc.
It seems the problem is the same as the wysiwyg-widget pluggin.
