First, I would like to check whether IE is using compatibility view. If so, to disable compatibility view in Internet Explorer 9, complete the following steps:
1. Open Internet Explorer 9.
2. Click Tools and you will see an option called Compatibility View.
3. If there is a checkmark next to Compatibility View, click it to remove the checkmark.

Hope this helps.
