I've just updated my main pc to Internet Explorer 8 to test out our website here. All seems good although I would make sure you turn on "compatibilty mode" under
Tools > Compatibility View Settings >Display all websites in Compatibility mode
If you are using IE7, you should try IE8 as it is faster and the pages here load faster, like when using Firefox.
Here is the IE8 site: Internet Explorer 8: Worldwide sites
