I think you will surely not be happy with IE8. I will not try ie8 within 2 years. IE7 is still not popular here in my country.
Well why not report the bug to MS instead of telling us about it? It's what the beta is for, finding and reporting bugs. Not just to see what the browser is like.
i did report it for your information, and why can't i tell you guys about it and discuss, its what general chat is for?
