When in the battlemap screen you cannot use your cursor under a certain point. It cannot go further down. That means you cannot click on various buttons needed for the battle which renders the game unplayable(disregarding the ridiculous notion of using auto-resolve in tips%tricks, as battles are 70% of the fun of the game).
