Issues w/ Compatibility

I am having an issue with my website where the header is being padded ~5px by Internet Explorer in Compatability Mode and I have no idea how to fix this.

Normally, this would only be a minor issue; however, I had some seasonal corporate logos going on the site and this padding really makes them look bad.

Any help you can offer would be more than appreciated.

I’ve attached 2 screenshots…

“Original” = how it is supposed to look

“with Compatibility” = padding issue
