To download the PDF to your desktop, you
have to right-click, select "Save Target As...", pick a place to save it,
and click "Save". If you simply click on a link, it will just download and
appear in the browser like a webpage. If you are still having problems it
may be that you don't have a PDF reader or new enough one to view the
file. To up-to-date your reader click on the link below:

Click "Download Now!" from the menu on the left-hand side of the screen.
Unlike Adobe Reader (20MB), this is only a 1.21MB download, which should
take only about 5 minutes to download over slow dial-up.
