Header display differences - MSIE vs Mozilla
 

I use Firefox when designing sites, but unfortunately MSIE displays the container differently than FF. What I am viewing in MSIE is 1 blank px on the right side of the header, and the menu bar extends past that blank pixel to the container's border. I would divulge the URL but this site's been live for quite some time and I don't want search results to come back to this site. ;)

I tried to add a bg behind the header to solve this, and it looked ok in MSIE, but the bg color extended way beyond the container border on the right. Very odd indeed.

If a mod wants to view the url, please PM me, thanks.
