I just performed an upgrade from 2.0 to 2.01 and the UI is broken in my preferences window now:

I did clear my cache this time around in Firefox the same way that resolved rendering related problems in Mint after my 2.0 upgrade.
I looked at the upgrade instructions included in the readme, but since I had already uploaded the ZIP and shelled into my server, used a slight variant: I renamed my app and pepper/shauninman folder and copied the updated mint folder on top of the existing install.
I’m also still seeing the ‘updates available’ link in the top left corner.
Any idea what might be going on?
