> Slow browser response when scrolling a large table with about 300 rows on IE7. It is because there is a :hover css class defined on a non-anchor (<a>) element. Removed it solved the problem. No problem for FF and Chrome.
> e.g. in the attached sample html, the below class will make the page scrolling very slow, even no DOM element applied this class.
> <style type="text/css">
> .foo.bar:hover {
> 		BACKGROUND-COLOR: #0000FF
> 	}
> </style>
> Searched the css in RF 3.3.2.SR1, below class caused the problem:
> .rich-list-shuttle-button-selection:hover
> .rich-link:hover
