It's best to first save these pdf's on a local directory on your hard disk.
You can try to download them right-clicking on http://www.pragma-pod.nl/showcase.pdf http://www.pragma-pod.nl/show-art.pdf http://www.pragma-pod.nl/show-dem.pdf http://www.pragma-pod.nl/show-man.pdf http://www.pragma-pod.nl/show-pap.pdf http://www.pragma-pod.nl/show-pre.pdf > showcase.pdf links to the other documents > do not work on my machine. As an alternative I can directly send the file to your e-mail address.
