I'm playing BTTF on the ipad. I'm trying to find out where Doc is, at the beginning of the game, in Edna's house. I get her out of the room by tapping on the radiator & start looking at the newspapers. When it gets to 1985, it stays on 1985. No matter how many times I get Edna to go to the kitchen & look at the stacks, it repeats 1985. How do I get past this? How many times do I have to keep getting Edna out of the room & look at the newspapers?
