The shop just put a new HD in my computer and now I saw a message saying the screen size was incorrect and it changed automatically so wide and tall I cannot see the outer frame with command bar etc. I cannot see any way to change it when I have no access except blind stabbling with the curser. It got me here butr where to now?
