While I'm not entirely sure of all the issues here, a good place to start would be a reset UI.
Given all the changes with this patch, it's really not a bad idea for everyone as a precautionary measure.
To do a full reset UI, you will want to save your addons in another spot if you wish to preserve them.
Then rename/delete or move your WTF, Cache and Interface folders while WoW is shutdown. Reboot your system.
Note, if you are running Vista make sure your permissions are set so it does not undo your changes.
More detailed instructions for different operating systems, including Macs are here.
