This was very frustrating to start with but I got over it.
What happens on my i5 laptop (Lenovo), Win 7 is:
I select full screen.
I have no idea what the (safe area) setting thing is?
Anyway, when I move my mouse to the extremes of the screen bottom or right say the screen scrolls over to reveal the desktop?
Most of the game screen is still visible and if I move my mouse to the opposite extreme it scrolls back a bit but there is always a bit of desktop showing. Any ideas?
My laptop is at its maximum res which is 1600x900
