Problems with admin functions

Having very weird problems with the admin pages. Most of it works and looks normal, but some things just don’t work anymore.

– Trying to attach media to a gallery, clicking attach moves me to the middle of the same page and does nothing else.

– Can’t reorder images in galleries, no drag and drop ability on any pages.

– Widget menus don’t work or drop down unless I turn on “accessibility mode”

I’ve tried re-installing, clearing my cache, and disabling all plugins to no avail. The problems are all so small and strange, I’m starting to suspect evil gnomes or something must be to blame.

Anyone else had this happen? Any fixes?
