moved site from sub-directory to root directory, admin menu still in denial

I was stupid and built a site in a dev directory. Now I've moved the site to what will be its permanent home, in the domain's root directory. I changed the $base_url in settings.php to the new domain, and added the code from here to the htaccess file, which fixed all the content navigation links, but my admin menu toolbar links are still trying to find the dev directory. I've searched all the admin_menu module files, and still can't find where it's saving this info.

Any ideas?
