Patrick, it appears this update has caused the site to stop working for regular users. I'm browsing with Internet Explorer, and from the World Home page, the drop down menus don't appear. From any other page (i.e. if I click GM Office to go to the Roster screen) the drop-down menus are fine.
This also makes me wonder if the iOS 5 fix only works from the World Home Page? Don't have any way to test that for you.
