Is hard to reproduce my situation in a test app, but if is need it, I would do it, because I am stuck here for days ☹

My pipe line looks like this: I have a **vtkRenderWindowInteractor** from over I setup

```
m_pInteractor->SetInteractorStyle(m_pInteractorStyleImage);

```

where **m\_pInteractorStyleImage** is **vtkInteractorStyleImageEx** type.

and _vtkInteractorStyleImageEx_ is

```
class vtkInteractorStyleImageEx : public vtkInteractorStyleImage

```

ok.

In this **vtkInteractorStyleImageEx** I got:

```
void vtkInteractorStyleImageEx::OnLeftButtonDown()
{
	int nPickPosition[2];
    this->Interactor->GetEventPosition(nPickPosition);
	vtkPropPicker* pPicker = vtkPropPicker::New();
	pPicker->Pick(nPickPosition[0], nPickPosition[1], 0, m_pView->m_pRenderer);
	TRACE("Pointer: %p\n", pPicker->GetProp3D());
	pPicker->Delete();

    vtkInteractorStyleImage::OnLeftButtonDown();
}

```

that is my testing code …
