In this game I'm writing, a cross between that old (QBASIC?) monkey game and the similar tank version, when you start a new game a form comes up so you can set the number of players, each player's name and each player's tank color. Then I draw the city using a series of line methods for the buildings. Only problem is, their is a whole in the city where the form was. Also, if a tooltip or similar thing goes over any of the spaces I've drawn, that space is erased when the tooltip goes away. What gives???
