Mysterious space in my header

[Awjvail]

Hi there

I've got a mysterious line break in my header/log in area, but it only occurs in Internet Explorer, and only when logged out.

Here's a screenie depicting it:


See how theres a space in between the header graphic and the log in area?

Here's what its supposed to look like (and what it does look like in Firefox):


I've searched high and low, and for the life of me, I can't figure out what is causing it.

Can you find anything that would cause a break in IE but not FF?
Here's my log-in area code.

PHP Code:
