Hello again,
The solution came to me after I sent this note. I ditched the extended
MouseRotate Class and called a method in the main from the body of
PickRotateBehavior and passed the TransformGroup rather than the
Transfrom3D. With this, I was able to use == in an if...then statement to
find a matching SceneObject instance.
