I get no messages at all when typing the command However, these appear from time to time without doing anything at all, but perhaps it's normal (no idea what it means).

It's so strange. I think it stopped working after I tried to install OpenSceneGraph crap and setting that up with the Terminal. Maybe some command there ruined something system essential.
