It guess I should have been more specific. I am using Window Maker as window
manager. I know that KDE has the Component Chooser and Gnome has its
gnome-control-center/preferred applications, but I have not found a window
maker equivalent. Frankly, I do not know if there is such a thing. 

Both KDE and Gnome have been told that I'd like to use linux-opera. Still, when
I click a link in bpm (bsd ports collection manager port), this event seems to
disappear in the eternal bit bucket and nothing happens. When I click a link in
a gaim chat window, mozilla gets launched. Openoffice.org insists upon firefox.

Why is this so messy? How do I change it?
