[JAVA3D] I need a little help removing a behavior.

I have a class that extends mouseBehavior. I think all is working fine, but I need remove the behavior of the view when the user press the second button of the mouse.

I have tried different ways but it doesnt work. Can you help me?

Im very very lost so give me an idea, please!!

Thanks in advance.
