Ok I dont remember how this happened but when I "maximize" a document, the part that's supposed to be gray is black. Heres a pic if you dont understand lol What the problem is I dont know how to make it from black to the default color (gray) Anyone know how to fix?
Under your black and white thing (At the bottum left!) you have a thing with two little square with a circle in the middle....under that you have a three square pi...try clicking on each one!!! Here what i mean!!!: Hope it help!
mine is grey and then after 1st f it turns to black and then i press once again and it went back to normal.
