There are three different sizes of courses supported by GopherGolf. 1) 9" monitor and 12" color monitor (7 x 7 grid) 2) powerbook screens (10 x 8 grid) 3) 13" monitor or larger (10 x 10 grid). Using GopherGolf, you should only open courses that have the same or smaller grid size as your monitor. Courses created on a 9" monitor will run on all other monitors but a course created on a powerbook may have objects placed out of view on a 9" monitor. You can simulate a smaller screen by holding down certain keys when you start up GopherGolf. If you have a powerbook or 13" monitor, hold down the '1' key to simulate a 9" screen. If you have a 13" monitor, hold down the '2' key to simulate a powerbook screen. When the courses are saved they will be saved at the size you simulated.
