I updated my site to 3.5.1 and now some of the editor buttons are acting strange.
For instance the LINK button in the visual editor when clicked does nothing. If you hit it again the screen goes grey and the link box appears at the BOTTOM of the page but it doesn't do anything or you can add a link but you cant exit from it. Also it doesn't offer any link searches.
To exit off the link button dialog box you need to fresh the page as cancel etc doesn't exit me from it.
I renamed/deactivated the plugins folder, and re-installed wp 3.5.1 and that didn't help.
