Hi Kristine!
Thanks for your feedback on the rendering of the new libsmi web site layout on Web browsers under MS Windows. As far as I know MS IE (even in recent versions) is known to be a quite bad implementation of CSS (W3C Cascading Style Sheets) and older incarnations of the Netscape Navigator as well.
I'm one of the guys who don't waste time on adjusting web pages so that they comply to Web browsers that don't care sufficiently about official W3C standards. Furthermore, I don't use any MS software at all, so that I simply cannot fix things that are probably easy to fix. In this sense, I can only suggest to use a better Web browser, e.g. Mozilla or Opera.
I'm sorry that I cannot give a more helpful response. Maybe someone else can...
