Now work in IE

As you might or might not have noticed, the site should now look way better (apart from the top menu) and also the dropdown menus in the sidebar should now finally work. Sorry for that, but I hadn't noticed that problem until yesterday.

What was the problem with the sidebar? Quite simple. I build the dropdown menus using DOM. There I had something like this to set the onchange eventhandler:

selectbox.setAttribute("onChange","redirect(this.value)");
