Javascript errors
On IE7+, when you want to open a menu (in issue list, the 'status' menu as example), it doesn't work and show an error saying 'this.menu.offsetWidth is null or not an object' (line 371).
On Firefox for me (could happen in others browsers), when you resize your window, Firebug displays a lot of the same error: 'this.menu.parentElement is undefined' (line 306).
All of these errors comes from vbulletin_magic_select.js file.
