Ok, I should clarify. I found out by right clicking and picking options I can change the background to any color. What I need to do is change the raster image that was inserted to white (it is currently black). On one computer both the background and raster insert are white and on another the exact same drawing they both come out black. There has to be a setting some where that I missed. Thanks.
Thank you for your question.
It sounds like there are transparent images in your file. Once you change the background color to white, the images became white, and if you change background color to black, the images come out black.
If this is not your case, please attach your test file to this post for deep investigation.
