Description:
The following line in monobook/main.css causes high CPU usage in Internet Explorer 7:

.TablePager tr:hover td { background-color: #eeeeff }

As far as I can see, this is used primarily on Special:ListFiles. However, it will cause slowdown on all pages, especially large ones. When scrolling down and hovering over links on http://en.wikipedia.org/wiki/Wikipedia:Deletion_review, it is quite noticeable.

Removing the aforementioned CSS rule fixes the problem.

Version: 1.15.x
Severity: normal
OS: Windows XP

The following line in monobook/main.css causes high CPU usage:
.TablePager tr:hover td { background-color: #eeeeff }

That line does not exist anymore in
https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/core.git;a=blob;f=skins/monobook/main.css;h=5866d97d041f6dd6114a9578c8383a2c1e02f4b5;hb=HEAD

Hence closing as WORKSFORME, but please add a comment if this is still somehow reproducible.
