> Key: RF-9416
> URL: https://jira.jboss.org/browse/RF-9416
> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Affects Versions: 3.3.2.SR1
> Environment: Windows XP. IE 7. Apache MyFaces JSF 1.2.8. Facelets.
> Richfaces 3.3.2.SR1
> Reporter: Alan Chan
> Attachments: ie_hover_css_slow_sample.zip

>
> 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
