Because I don't have Netscape installed on my computer, the help function of Staden doesn't work automatically. During the staden course James told be to look into /usr/local/staden-linux-rel-1-4/lib/tk_utils/help_netscape.tcl
I might do so, but as a quick fix I made a symbolic link to mozilla: sudo ln -s /usr/bin/mozilla /usr/bin/netscape
And this really works. I also tried it succesfully with Konqueror: sudo ln -sf /opt/kde3/bin/konqueror /usr/bin/netscape
