Internet Explorer 9 tabs are not displaying full description of page unlike IE8.

Is there a way to display the full text description of a page on IE 9 tabs? It used to be fully visible on IE 8. It is important to our users that they see the full description. See sample screenshot below: top image is IE8 and below it is IE9. <o:p></o:p>

Any help is most appreciated.

Thanks.
