Unfortunately now the smoother doesn't work any more and many small cubes appear which make the whole plot not very nice. Can I remove these small cubes and tell the smoother to work, without making the program unperformant again ? Tia Marcel -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ Bitte lächeln!
