It seems to be strange: If the view is far from a shape, the ambient light reflexion is OK. If the view is near the shape(zoom), the ambiant light is shown only wh en another shape approaches. Changing the boundingSphere radius change this behavior I tried directx and opengl runtime, it did not change anything. It might be a weird behavior like u said!

There is no code in VisAD to delete or modify the AmbientLight. It is possible for appliation code to call the getRoot() method to get a reference to the root, then to delete or modify the AmbientLight. I sincerely doubt that your code or Ugo's does this, so this may be some weird behavior of Java3D in Applets. I can't see any connection to mouse clicks. If you can come up with any more evidence about what is going on, I will look into it.
