Working on a wordpress template that will be used throughout the site, and it works fine in firefox now, although I had a heck of a time trying to get even that to work. IE7 has some weird padding issues on the right of the header... 30px instead of 15px. From what I can see in IE6 the same problem exists, but only when I add "_height:100%;" to the div#wrap. I probably am making this overly complex and need to take a step back, but don't have the time.
To add to your woes... it appears that you have a padding issue on your horizontal nav bar as well. In Firefox you're pushing about 50 pixels off the right of my screen, and making me lovely browser scroll horizontally.
