<DIV> </DIV>
<DIV>Thanks for the answer and hit. It worked better. But, now I get both effects in case the hardcore binded keys (like w, e) just like in the demo. Guess I cant change that. However, If i click the mouse , it does not rotate the actor anymore (as it does without the my interference with the events). I added an observer and the mouse event is catched but the effect is not there anymore :(. My class is derived from vtkInteractorStyle.</DIV>

<DIV>Another junior question: what is the reason of the "forward event" -> the function call you suggested. </DIV>

<DIV>Thanks,</DIV>
