Background Colour

[Mick Sulley]

The background on the code edit window is light grey.  My eyesight is 
not what is was and it would be easier for me if I could change it to a 
white background but I cannot see how to do that.

I have looked at Settings > Preferences > Editor > Style and found many 
things I can change but cannot see how to change the background.  Anyone 
know?

Thanks

Mick
