I recently downloaded Cosmos UI for World of Warcraft just to try it out, and decided to delete it after deciding I didn't like it. So I trashed the WDB, WTF, and Interface folders. When I relaunched WoW, there was still a vertical toolbar on the right left over. So I deleted the .pref files for WoW. Relaunch, and it's still there. I decide to repair permissions on the off chance it might fix the problem. It didn't. So I trashed the entire WoW folder, and reinstalled. After spending hours doing the reinstall and downloading patches, I launched WoW again. The vertical toolbar is still there. Short of formatting and reinstalling OSX, I have no idea what to do. I hope I've just made a stupid mistake, and there is a quick fix. Any help would be appreciated.
