I found this advice on the Microsoft website:
Some websites may have been designed for earlier versions of Internet Explorer. Try to view the website in Compatibility View.If Internet Explorer recognizes that the webpage isn't compatible, you'll see the Compatibility View button on the Address bar. Try clicking it.
In Compatibility View, websites will be displayed as if you were viewing them in a previous version of Internet Explorer, which will often correct display problems. You don’t need to click the button for a site after you’ve done it once—the next time you visit the site, Internet Explorer will automatically show it in Compatibility View.
