Upgraded to 3.5 – Links in Dashboard Not Working

Good evening. Today I upgraded my site to WP 3.5 and the following doesn’t work:

1. The menus along the left column no longer “drop right.”
2. I can no longer click to select all of items (plugins, images, etc)
3. I can no longer reply to comments through the dashboard (but I can approve)

I’ve deactivated my plugins, changed to Twenty11, and these problems haven’t cleared up.

I’m not tech savvy and I’m at a loss as what to do next. Thanks for your help.
