Which Main City screen do I press B on? I've tried pressing b when on the screen where I can advance the night/visit all the buildings, but nothing happens. Maybe it's not the right black screen bug? I have this bug where about 2/3 of the window is covered in these black specks. They don't really interfere with seeing what's underneath, but it is annoying. Also, it always occurs if I change focus away from the game. Also is there a more up-to-date walkthrough than the ones on the front page? 2 of the links point to the exact same walkthrough.
