That worked - great!
Still had the problem that the change to 'width: auto' in the main.css expanded the footer beyond the frame on all but the product pages, So I restored my old main.css and that fixed the alignment on all the non-product pages but shrunk the footer too far on the product pages. So I added the' width:auto' to the style section of the product pages only - not main.css and voila - all pages are aligned now.
Now the only small issue I have left on this: some weird stray stuff at the top left(under the logo) on http://outofchaos.net/gsc/www/products_results.php?Category_ID=32 - see attached where I highlight it. It's nice and clean on http://outofchaos.net/gsc/www/products_detail.php?ID=4 which is how I'd like it to be on the products_results.php
Can you spot what could be causing that?
Thank you again - your support has been awesome.
