Why don't some websites display correctly in Internet Explorer 9?
Websites that were designed for earlier versions of Internet Explorer might not display correctly in Internet Explorer 9. However, you can often improve how a website will look by using a feature called Compatibility View.
When you turn on Compatibility View, the webpage you’re viewing—as well as any other webpages within the website’s domain—will be displayed as if you were using an earlier version of Internet Explorer.
If Internet Explorer recognizes a webpage that is not compatible, you will see the Compatibility View button on the Address bar. To turn Compatibility View on, click the Compatibility View button to make the icon change from an outline 
to a solid color 
.
From now on, whenever you visit this website, it will be displayed in Compatibility View. However, if the website receives updates to display correctly in the current version ofInternet Explorer, Compatibility View will automatically turn off.
Note :
Not all website display problems are caused by browser incompatibility. Interrupted Internet connections, heavy traffic, or website bugs can also affect how a webpage is displayed.
