Last time I used PCB123 it was version 3 and I could print without the background printing black.
I installed v4.125.0 and using files created in v3 (not tried creating a new file, yet), I have set background to be invisible in the display settings but it shows on the screen and prints black.
I can change the background color to white and the screen changes BUT ALL the schematic turns white and cannot be seen.
Pale blue (for example) shows the schematic against a pale blue background but, like black, setting the background to invisible does not change it.
Running Windows 7 with an Nvidia 7950 GT video card.
I do not have v3 setup to try the earlier version.
Any help appreciated.
