This is my first post, so I am not sure I am in the correct place, but here goes.
Have a Z4 with MKIV , V32, Navtweak, UltraISO, & ImgBurn.

My eyes are not as good as they once were and need to set the background colors to white. Have been able to do that on the split screen, but not on the full screen. Have looked at almost all of the postings and it is either not there or I have missed it.
