Not sure what this icon is called but whenever i open up my archicad on my Macbook air to full screen (never had a problem and i've had it for two years) a type of arrow shows up around a certain perimeter of my screen and if i put my mouse inside this perimeter i cannot click any controls. I have attached a photo as i'm not sure how to explain this. Have i got a setting on that shouldn't be on? Help!!
