Oh my, Lennart cripples computers. I should be banned. Just like DRM!

vi has static config files. They are only read on vi's startup. 

OTOH GNOME usually does instant-apply. I.e. what you configure is

Are you sure you can log in twice on Win2k as exactly the same user id?

Nah, if at all that's the job of the dm or the sm, not the wm.
