This site was designed to be viewed with Netscape 6.1. If you would like to update to 6.1, you can do so here.
For some reason, Netscape 4.x browsers do not show the vertical scroll bar on the right side of the browser for the longer pages, and this is not something I can fix, it is design flaw of that browser. I would suggest viewing the page with Netscape 6.1 or Internet Explorer 5.0 or newer.
