I'm afraid I'm not able to parse the above.  Do you have a ref_ptr<> to the
camera manipulator in your application outside of the View/Viewer handle to
it?  What CameraManipulator are you using?

Could you create a small example to illustrate this usage case?  I've been
reviewingan testing all the CompositeViewer/View and associated examples
today but haven't yet come across an example of usage case they is causing
the problems.
