I'm having trouble getting a site to look right and need help.

URL: www.nationwidejustice.com/index-test.htm
Problem: the search site field in top left

When you look at it in Internet Explorer there is a big space around the field. In Firefox there is no space. I don't want that big space in IE either because it looks rediculous.

I tried making the text field's width as small as '1' and it didn't remove the space, which tells me it's not a width problem.

I have no idea what it is. Can anyone help please. I'm baffled!
