Upload/Insert Image, Media, Audio, Video Not Working

Hello:
My wordpress blog is acting very strange today. It’s slow and if I hover over “Screen Options”, “Help” or “Howdy Admin” nothing happens when I click.

Same thing with the Upload/Insert Image Icons – nothing happens. I use Thesis and my wordpress blog and theme are all current with the latest versions.

The wordcount says zero, but I have a complete article typed.

The other day, bluehost contacted me about a malicious plug in something to do with Tim Thumb which I have no idea what this means.

I shut down my pc and logged back in and it’s the same thing.

I would really appreciate any help you can give me.

Thank you in advance.
Janie
