Bottle of Champagne if you fix HTML/CSS issue

Steve needs help:

"Right. This is your last chance to save bowblog's three-column layout. Most of you (the Explorer users, basically) don't even know this is a three-column web site because, for you, the third column displays somewhere down there (underneath the left-hand column). Some of Britain's finest minds have examined my CSS and HTML and no one seems able to fix it so that the right-hand column displays where it ought to over there on the right (although the esteemed Phil Gyford did improve things markedly). So (trying not to sound desperate), if you reckon you've got what it takes, why don't you sort it out for me and I'll send you a bottle of Champagne (own brand, natch). I guess you can just view source if you need the HTML and here's my stylesheet."
