Thank you for reporting this issue with IE8. Such help is highly appreciated, because we are collecting a list with behaviors and bugs with new browsers and once the browser is officially released (as in the case with FireFox 3, Safari 3, Chrome) we release a special hotfix for these browsers in a fortnight. At present we are not able to provide you with a custom solution, because as it is stated in our browser support policy we do not support browsers in beta, and as you know at present, it is Beta 2 of Internet Explorer 8 and they have a long way to go until releasing it officially.
