I just got the Logitech Dinovo Edge Mac Edition about 2 days ago and it seems the Itunes buttons don't work when Itunes isn't the active window. Is it my keyboard or is there a fix? And also, is it possible to have the f9,f10,f11,f12 buttons working without hitting the fn button? When I try and modify what the key f12 does, it allows me to have it work without fn, but search still comes up. Any way to stop this?
