gosh, that's really radical.
my 70 year old mother-in-law who i left with some card games on debian with fvwm (no gnome trash for me!) managed to quit them by mistake...
... and then managed to work out on her own how to run xmahjong.
i have to say that i'm really, really impressed.
fvwm is one of the lightweight window managers that doesn't obviously have menus or anything. i like it because running programs (with an xterm) is really unobtrusive.
