As reported by my pal Walter, IE8 Beta 1 indeed failed to rendered the all popular Hotmail web page properly. This prompted me to do some testing myself.

 
Yup, just as said, position all ‘koyak’, now let me try it in IE7 mode

Alright, now it is working. And seriously speaking, I feel the rendering in IE7 mode is faster than the original IE7 itself. Someone please help me bust this myth!
