I use AlphaCAM and the background color is black.  I can change the background to white and use black lines.  Anyone know the best way to set it up?

In general, it's better for your eyes to use the darkest background possible. Most people fail to realize that a computer monitor can be as bright as a light bulb...and you're staring at it all day.

Good point, maybe I should just stick with the black. It works fine but it's the only program that has the black.
