black margins down each side of my screen, so reduced screen size, can anyone help please?
I have 2 black margins down each side of the viewable sceen, I've tried going in to 'full screen mode' but all tha happens is that I lose my footers and headers, the screen view still remains long and narrow rather that filling the screen top to bottom and sise to side. Can anyone help please?
MacBook Pro, Mac OS X (10.7.4)
