[vtkusers] vtkInteractorStyleTerrain not compatible with vtkAxesActor/vtkOrientationMarkerWidget ?

[pof]

Dear vtker's,
No answer yet, so does it means that I'm now the only one having this 
problem ?
Herebelow is a small example program that illustrate this 
incompatibility between vtkInteractorStyleTerrain and 
vtkAxesActor/vtkOrientationMarkerWidget.
Any idea/comment ?

////////////////
#include "vtkCylinderSource.h"
#include "vtkPolyDataMapper.h"
#include "vtkActor.h"
#include "vtkRenderer.h"
#include "vtkRenderWindow.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkProperty.h"
#include "vtkCamera.h"
#include "vtkAxesActor.h"
#include "vtkOrientationMarkerWidget.h"
#include "vtkInteractorStyleTerrain.h"

int main()
{
     // Creates a polygonal cylinder model with eight circumferential 
facets.
     vtkCylinderSource *cylinder = vtkCylinderSource::New();
     cylinder->SetResolution(20);
     cylinder->SetCenter(0,0,0.);
     cylinder->SetRadius(10.);
     cylinder->SetHeight(20.);
     vtkPolyDataMapper *cylinderMapper = vtkPolyDataMapper::New();
     cylinderMapper->SetInputConnection(cylinder->GetOutputPort());
     vtkActor *cylinderActor = vtkActor::New();
     cylinderActor->SetMapper(cylinderMapper);
     cylinderActor->GetProperty()->SetColor(1.0000, 0.3882, 0.2784);

     vtkPolyDataMapper *MeshMapper = vtkPolyDataMapper::New();
     vtkActor *MeshActor = vtkActor::New();
     MeshMapper->SetInputConnection(cylinder->GetOutputPort());
     MeshActor->SetMapper(MeshMapper);
     (MeshActor->GetProperty())->SetInterpolationToFlat();
     (MeshActor->GetProperty())->BackfaceCullingOff();
     (MeshActor->GetProperty())->EdgeVisibilityOn();
     (MeshActor->GetProperty())->SetLineWidth(2);
     (MeshActor->GetProperty())->SetColor(0.,0.6,0.8);
     (MeshActor->GetProperty())->SetRepresentationToWireframe();

     // Create the graphics structure.
     vtkRenderer *ren = vtkRenderer::New();
     vtkRenderWindow *renWin = vtkRenderWindow::New();

     renWin->AddRenderer(ren);
     renWin->SetSize(600, 600);

     vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
     iren->SetRenderWindow(renWin);

     // Add the actors to the renderer, set the background and size
     ren->AddActor(cylinderActor);
     ren->AddActor(MeshActor);
     ren->SetBackground(0.1, 0.2, 0.4);

     // We'll zoom in a little by accessing the camera and invoking a "Zoom"
     // method on it.
     ren->ResetCamera();
     ren->GetActiveCamera()->Zoom(1.0);
     renWin->Render();

     vtkInteractorStyleTerrain *styleTerrain = 
vtkInteractorStyleTerrain::New();
     iren->SetInteractorStyle(styleTerrain);

     vtkAxesActor *Axes = vtkAxesActor::New();
     Axes->SetShaftTypeToCylinder();
     Axes->SetXAxisLabelText( "X" );
     Axes->SetYAxisLabelText( "Y" );
     Axes->SetZAxisLabelText( "Z" );

     vtkOrientationMarkerWidget *AxesWidget = 
vtkOrientationMarkerWidget::New();
     AxesWidget->SetOutlineColor(0,0,0);
     AxesWidget->SetOrientationMarker(Axes);
     AxesWidget->SetInteractor(iren);
     AxesWidget->SetViewport( 0.0, 0.0, 0.2, 0.2 );
     AxesWidget->SetEnabled(1);
     AxesWidget->InteractiveOn();

     // This starts the event loop and as a side effect causes an 
initial render.
     iren->Start();

     // Exiting from here, we have to delete all the instances that
     // have been created.
     cylinder->Delete();
     cylinderMapper->Delete();
     cylinderActor->Delete();
     MeshMapper->Delete();
     MeshActor->Delete();
     ren->Delete();
     renWin->Delete();
     iren->Delete();

     return 0;
}
