Header Width Issue (Lightword theme)

Okay folks,

Got another question (boy, aren’t I just full of questions lately). I’m using the expanded Lightword theme which added a second sidebar. Under the Lightword options, it says that the max width of a header image is 796px. What I want is to have my header stretch all the way across the top of the page – when I uploaded a wider header, it shows up, but it’s not placed correctly at the top of the blog (it’s not centered and not butting up against the top of the blog). I’ve scoured the css for whatever issue that sets the width at only 796px, but I’m not finding anything.

My website – http://www.sixfootditch.com

Any help or suggestions on how to get my header to sit in there correctly would be greatly appreciated.

Thanks!

Jer
