++ Added addEvent function to run clickMenu on window.load
++ Changed clickMenu so that the onclick happens to the H2 tag rather than anywhere in the DIV tag - so clicking on the text would hide the text
++ Added a class "cls_noscript" (see c1text.css) to default to showing the text and hiding the +/- when Javascript not available
