Somehow, all stuffit-archives have been associated with internet (the default browser). How do I choose wich program to open a file with a certain extension (associate files manually)? MxM

Right click on the file and click on Get Info Under "Open With" change the default program.

1. I have no right-button on my mac 2. Under Get Info is no "Open With" MxM

Hmmm..yeah, that was OSX advice..wouldn't work for you.. Firstly, how do you know they're associated with your browser? stuffit files usually have a little picture of stuffit on 'em if they're properly associated, but some browsers keep an expander folder in their folder... At any rate, to reset your associations, open up expander and click 'preferences', scroll down to the last selection (Internet config) and click on the button that says "use stuffit expander for all available file types".. If you haven't set your internet config settings at least once this option won't appear, so you may have to do that first..you should have internet config somewhere on your drive, either in the quicktime folder, or the internet folder, or netscape etc.
