The header/footer is where I'd been changing it, but there's nothing between the 780 and 1,000 for options. Although I think most people have a wider screen these days - there are still some dinosaurs out there

(when our flat screen desktop monitor died...we had to bring out our old one which is the smaller screen resolution) - the only plus to it, is I get to see how the site looks in both resolutions (desktop & laptop).
When I manually change the width in the frame.html in template/layout 5...it's changing spacing and dropping indents in the left product bar, and also throwing off the space on browse by price/manufacturer and search options (must be other places/templates to manually change widths). Anyways - sticking with "screenwidth" option and just using what's offered in the drop down

- thanks for your help though.
