Hi there, I sometime use my MacBook on a big LCD screen. To do so, I press F7. The problem has just started today, when switching on my computer, All the desktop icons appear wider than usual and the icons from the left part are missing (as if I had my laptop connected to the LCD screen before pressing F7), pressing F7 doesn't solve the problem. What can I do to restore the normal view? BTW all the laptop keys work fine.
