boybianchi on "no visual editor"

Hi,

the visual editor is not working for me.
to be clear: i can click it, but nothing happens. It just stays in the text editor.

Here's what i tried:

updating wordpress from 3.5.1 to 3.5.2 (it was on the to do list anyway)
trying different solutions i found in the forums such as deactivating every plugin, etc
switching to twenty ten theme to see if it is theme associated or not
cleared my cache

so far no luck. Any thoughts on what i can try next?
Thanks!
