Took a lot of finding, but got there. Recently I was working on removing all the div's because they didn't look right in all browsers. While trying out a few different web development tools on my new mac mini I accidentally put things live well before their time. Turns out there was a spurious width property on one of the tables. Doh! Never mind, all sorted now.

Also had problems with the alignment of any content that had tables embedded within tables so that took a bit of playing about with. Haven't tested it with anything other than Safari since it's getting late. Will try and check it all out in Firefox and IE tomorrow.
