Yes, Clipka, you are right, once more. I see what you mean. Great
advise, very helpful, and i really thank you for this advise, highly
appreciated.
I made a change to the scene, and put the macro object inside a union,
with the result that the scene now functions but nothing than the
background appears on the screen. :-D
Here's the updated scene code on which I am breaking and smashing my brain:
