Hi Alvaro,
MouseZoom uses WakeupOnBehaviorPost() and shoudn't
have this problem. It may be other things in your
scene graph that cause the problem. Which version
of Java3D are you using ? Please try the latest
v1.2.1 beta2 to see if it works.
Attach is an example modify from
HelloUniverse (after disable the rotator) and
the MiMouseZoom as describe but we can't reproduce
the problem. Can you please send us a test case
for this ?
Thanks.

>Hi!,Kelvin.
>I tried to solve the problem of the class which extends Canvas3D and
>consumes 100% of CPU.
>I´ve made three class which extends MouseRotate, MouseZoom and
>MouseTranslate.
>The code is like this:
>class MiMouseZoom extends MouseZoom{
>
>public void initialize(){
> wakeupOn(new WakeupOnElapsesFrame(0,true);
> super();
>}
>}
>
>but It already consumes 100% of CPU!
>Can someone help me!
