Yes. Thanks.
I have fixed my code. I was just wondering if NSCells
had to do it automatically but obviously the cannot know the background

I have difficulities to see what is the standard OpenStep behavior

Who should call +NSMenu popUpContextMenu:withEvent:forView: ?
I see this feature is not yet implemented, but should not be too hard.
I could give it a try. Has anyone taken that ?
