I moved my breadcrumbs to the tpl_header as my design required that they be aligned left above the category navigation. I still want the background color for my right column to extend to the top immediately below the category tabs. I have tried a bunch of different things without success (width of the breadcrumbs, z-index of either the breadcrumbs or the right column). I even tried to create a background image with the 150px wide to the right of the color to fill in that space. No luck (in safari and ie the background doesn't align with the column like it does in firefox). Any other ideas?
