so my friend just got a mac mini and uses the logitech mx3100 set for keyboard/mouse. i guess she was trying to assign some exposé commands to the extra buttons and somehow made it so that every mouse button is an exposé command and now she can't click anything. lol. is there any way to reset the system prefs or something at startup so she can go back to the default settings? i know about zapping the PRAM but i'm not thinking that would work for this.
