Search box floats down in IE7

I am using a Wordpress-based theme for my site. When I use the search box that comes with the theme, everything works fine. But when I use Google Search box, it floats down. You can see the site here: http://www.shoutpedia.com

I tried different options bu开发者_高级运维t none of them worked.

There is no push down in Firefox, Chrome, Opera and IE9.

Does anyone have any suggestions on how I might fix this?

It's because your ul.nav class is pushing full width. You have a ul.nav css style set to display:inline-block. Try removing that.
