/* CSS HACK: position:relative needed by IE6 otherwise the header and col 2 don't show up on initial rendering - they're there but you have to minimise the window or switch to another app and back to see the full effect. But IE5(pc) doesn't like it. And nor does NN4.
NB. the use of pos:rel has to go way beyond skin-deep - any nested element that needs a background colour appears to require to be be relatively positioned */
