The Wolf-Villain model for growing surfaces is investigated using the height-height correlation function and the structure factor. Both functions show an unusual scaling behaviour that can be attributed to the time dependence of the average step size and is characterized by a new exponent. A modified scaling law is introduced which may describe quite generally the crossover behaviour in models of this kind. It leads to a very different classification of the model than has been inferred from the exponents obtained by measuring the width of the surface as a function of time and system size.
