[vtkusers] vtkInteractorStyleTrackballCamera problem with multiple views

[Oleksandr Malyushytsky]

For some reason I can't see my question in mail, so I am not sure was it
posted, but was not replied or never ended up in the mailing list.

1. Could anybody confirm that it was posted on mailing list?
2. Can anybody give a hint how to notify interactor style (reset mode) when
even propagated to other widget?

Best regards,
          Alex
