Some SD Users only see Mobile View
We're running ServiceDesk 7.1 SP1 and I have several users, who upon login, are presented the mobile login, and mobile view portal pages. Trying to navigate to any non-moble page results in an error (can't remember it off hand). They are running IE9.
I have them open IE Developer Tools (F12), and look at the current "Browser Mode". It's set to IE9 Compatibility view. If I change the browser mode to IE9, IE8, or IE7, the page refreshes and they now see the standard portal view pages.
Anyone come across this issue? I can't very well tell the other odd thousand or so users to open Developer Tools and change their browser mode. I'm guessing I can add a strict <!DOCTYPE> somewhere, but any idea where I would do it? In the IIS directory? Which page?
Any help would be appreciated.
