How do I change the background color of the design window?
There are two ways to change the background color. The first is to use the Design tab of the Settings dialog (File | Settings). This provides a wide choice of background colors. You may alsp need to change the grid settings to set the color of the grid to one that contrasts with the new background color. The second way is to change the environment (datamine.env) file and the guide.aim file. This only provides a white background.
