[vtkusers] Issue with vtkInteractorStyleSwitchBase and vtkMFCWindow

[Doug Hoppes]

Thanks for the answer, Marcus... however, this is in the VTKMFCWindow code that is shipped with the source code.  Should we override that code?

This is a warning generated by that class to warn that interactor styles likely won't behave the way you expect. It was requested due to interaction silently failing in applications, you can fix it by linking to vtkInteractionStyle which will provide the expected override.
