Martijn Apparently the whole thing is unfixable, Internet Explorer will not let its user have any effect on what document mode it uses to display websites. Who ever came up with that!?

Mark Dain Something I've just thought of; what version of IE? I believe rendering modes were removed (or at-least deprecated) in IE 11. Everything is suppose to use edge mode now

Martijn IE 11 on Windows 8.1 here, so seems like they're all still in there
