Changing Background Colour of Drawing View in Studio 7


I just upgraded from 5 to 7, but I don’t seem to be able to change the background colour of my drawing view the way I could in 5.

From “Preferences” I select the “Interface” tab, wherein I change the colour of the drawing view to a light manila colour (as working with white is hard on my eyes). I then click “OK” to close the colour selection circle and then “OK” again in the “Interface” tab, but the colour of my drawing view remains white.

Even if I shut TBS7 down and restart with the changed settings, the background remains white. Preferences shows I have changed it to manila, but the actual drawing view remains white.

Am I forgetting a step here?
