<form> tag issues

Ok, so here’s the deal. I’ve got a menu bar setup for the top of my page. And I’ve inserted a search box. However, when I insert the <form> tags, IE and Firefox will push the items in the cell below it down too far. It basically looks like its sticking in an additional line break. When I remove the <form> tags, it looks just fine.

To see a live version of the issue I’m talking about, checkout this link.

The top bar needs to be a total of roughly 92px high. With the <form> tags, it pushes it well over 110px high and you can see the gradient background starts to repeat.

Any ideas?
