As far as I've seen (I've tried many times), it is a once per session
behaviour : if it starts OK, it will stay OK.

The good sign is to look at the x,y,z axes that are drawn as cylinders
even if the molecule is represented as lines :
- if they are in colour since the beginning, then the molecule will display OK
- if they are B&W, the molecule on the lower screen will be B&W
- if only the letters x,y,z show, the molecule won't be drawn on the lower
  screen.

Yes, I'd be glad to test it and maybe find track of this problem.
