Having downloaded & installed the latest beta of Internet Explorer 7 (and deciding that it really isn't worth me using it instead of Firefox) I noticed that while most of the CSS bugs that IE6 had rendering this site had been fixed, one persisted to IE7. As such I've added yet another conditional comment to the source to make IE7 load a separate CSS file. It only makes one minor fix (i.e. hack): the thick border on the top of the navigation tabs at the top of this page don't render properly unless I set them to be positioned relatively. I don't even have to move the element anywhere, just tell it to be relatively positioned. I really do give up with IE rendering bugs. Not to say that Firefox is perfect or anything, but it's a hell of a lot better...
