Some earlier versions of IE have problems with the box model, but I don't see it at all in my tests. :/
I actually tested with IE6 to 9 on a version without the extra space, yet there were no visible problems.
(Is this below IE6? Because then a browser specific style sheet is probably required.)

Perhaps it's a DPI setting issue. In that case, the only real solution would be making things more fluid.
I'll work on this and see what I come up with, because it should solve the problem with the button below the search field.
