[vtkusers] vtkInteractorStyleTerrain not compatible with vtkAxesActor/vtkOrientationMarkerWidget ?

[pof]

Well,

it looks like the described bug vtkInteractorStyleTerrain did not 
attract any developer.
I might give up using the vtkInteractorStyleTerrain and replace it with 
vtkInteractorStyleTrackball as this problem does not occur in this one, 
though the behaviour of vtkInteractorStyleTerrain much better fits my needs.

Any idea, maybe from the vtk team ?
