IE7 problem with Sliding Tabs

I'm having a problem with my sliding tabs in IE7. I'm using these sliding tabs (http开发者_StackOverflow://www.queness.com/post/274/jquery-sliding-tab-menu-for-sidebar-tutorial)

You can see the problem on my site (http://wpmaniac.com/leetpress/) in the sidebar under "Latest Reviews".

The sliding tabs are working fine in all other browsers. I can't seem to figure out what the problem is in IE7.

Here's a screenshot of what's wrong in IE7:

Thanks

It seems like an overflow problem to me. Here's what I would try:

#panel
{
  overflow: auto;
}
