Tabs on home page not working IE7, IE8

Hello,

Having a little trouble with the content tabs in BP Daily. They're not working right in IE 7 or IE 8. They are working just fine in FF, Safari, Google Chrome. Seems to be a CSS issue but I can't seem to locate it so I thought I would ask here. I did set different widths for the two columns, the main content column is a little smaller. Thanks.
