I have come across a site which is completely broken with IE9. It works smoothly in Firefox, Chrome, Opera and IE6/7. So, using the compatibility view doesn't work either. However, if I open the developer toolbar and force the page to render in IE9 Standards Document mode, then the page displays perfectly. So, I want to know if there is a way to always force it to render in IE9 mode instead of the default Quirks mode?
