Looks the same in NS as it does in IE, to me at least.
My only suggestions would be to; carry that Global Nav at the top of the Home Page across the entire site, rather than the current Return Home links. I'd also standardise where the content sits on the page; on some it is as on the home page, others it is higher up the page - also standardising the width of the content background will make for a more streamlined experience for the user.
Finally, the Home link on the Feedback page doesn't work.
It'd be worth your while downloading several alternative browsers for testing, I know it's a chore but it makes for better results at the end of the day - without having to rely on third-party comments (although these are always useful at some stage of the build/deployment of a site). TFC Nothing is a problem for me...
