After launching Claris CAD or MacDraw II on a small start-up monitor and moving the window to a larger monitor, the window on the larger screen cannot be resized.
Both Claris CAD and MacDraw II set your window size to the size of your start-up monitor. The window size is set at this point and CANNOT become any larger. A work around would be to change your start-up monitor to the larger monitor and then launch Claris CAD or MacDraw II.
