Seriously?? :) Of course the layout is wrong. IE6 is ancient and probably one of the worst pieces of software in history. Even Google started campaigns to help people drop it already.
I don't see any reason someone should still be using IE6 or IE7 these days and I really don't think web2py should provide support for any IE below IE8. If I even think of all the hacks I had to use back in the days to make this "browsers" work properly... I still need to use all kinds of time wasting techniques to make IE8 and IE9 behave remotely like a modern browser, but IE6... Come on! :)
