Hi Wolfgang, 

Indeed your solution works without any flaw…
Looking at your code, I learned that Overlaybox is an object which can be filled with a background color, as in:
	fill OverlayBox withcolor lightgray ;    
so that the background can be in color.

Should we add this kind of problems and solutions to the wiki?
If yes, I am willing to do so.

Best regards: OK
