Cannot view CSS error in Internet Explorer 8

I've been trying to track down a problem in Internet Explorer. My client sees the products on a certain page as all stretched out. I can view the pr开发者_如何学Gooblem via http://ipinfo.info/netrenderer/ but not in an actual PC browser with Internet Explorer 8. How can this be tested and then fixed?

I can see the problem using IE8. However, when I turned on compatibility mode it went away. Check that you are not running in compatibility mode for this site.
