Natural Studio Background Colour

Is there a way to change the background colour of the map editor?

I am running Natural Studio 6.3.8 on Windows 7

I guess the color comes from the windows theme…

I’ve tried changing several parts of my Windows theme, but none seem to have an effect .

I noticed that there was an .ini file that could be edited for Natural Engineer to change background colours. I was hoping there was something similar for Natural Studio.
