If you are using Google Website Optmizer Control Script to test and improve your website, be careful about where you place the control script in your html page. IE won’t like it if the script is placed before the Document Type Declaration. IE might render the content in distorted form severely impacting visitor experience.
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd”>
Just put the control script after the Document Type Declaration and you should be fine.
