Mouse pointer can't reach right side

Mouse pointer doesn’t move all the way to the right. Running on MacBook Air. The game worked properly previously. Now when it first starts up, there’s a black window (not full screen size) that appears first. Seems like the game thinks it’s running in that smaller window. Looks to me like the right hand side of that screen is about as far as the pointer will move. it’s not playable now.

Hey Vulgarr,

Can you try the steps listed here?
