Charged my new iPod (fresh out of the box - away from my mac) using the cradle plugged into the wall - seems to continues charging even when full. When I took the iPod out of the cradle it turned on, even if I turned it off before putting it in the cradle. Its a bit of a pain because if you put it in the cradle off and locked you have to unlock it to turn it off again. Does anybody else have this or is it just mine? Am I missing a a setting in Prefs?
