I've been looking at this for a couple of hours now and I'm just not getting anywhere. I am working on a new site and am having trouble with the right column of sideboxes. In Firefox they display correctly but in IE6 and IE8 there are certain pages where the center column is not taking up the full width and the right column is not over on the right edge.

Any help appreciated, it's currently driving me nuts!

Thanks
