The next version will work in Netscape 5 as well...

There's only one version of this script now, and you can choose
whether you want images or not.

To change where the menu appears change the left and top values of the divCont
in the stylesheets, it's currently placed relative so you can
place this menu in tables or similar if you want. Change the 
text colors and size in the A.clMain and A.clSubb classes.
