I created a project in Apple Media Tool to run on a PowerBook 540c. The screen preferences are set to 640x400 pixels, and the PowerBook is set to thousands of colors, but when I run the projects I get an error message saying that I need a larger monitor, or a monitor that supports thousands of colors.
Some PowerBooks actually have a vertical resolution of only 399 pixels instead of 400. In these cases, a 640x400 project will not run. To correct this, the project must be created or altered for a vertical resolution of 399 pixels.
