Did upgrading to 3.6 beta work? I’m having this exact same problem. I just get a square in the top left corner which when dragged messes everything up BIG TIME! I’m using the GrandMag theme from IndustrialThemes (Premium) but they’ve removed the theme since and are in hiding. Also, this is a site for a client with alot of work gone into it and a week from going public.
I knew I shouldn’t have upgraded! Idiot! There should be a rollback option in WordPress!Or a plugin test mode before you commit.
