Style sheets

I've upgraded the style sheet for this site. I did so because I discovered a "bug" in the previous one I was using under IE 5.5, this style sheet works fine with Camino and IE. It's not that I'm a IE fan , but most of the world does use it, that a pitty because support of CSS2 is poor and I need to tweak my sites in order to have theme behave nicely in Microsoft's Browers ...
