[vtkusers] Picking Coordinates with the Mouse

[John Vard]

Dear User's

I have a question regarding Picking with the Mouse. I've disabled the general 
vtkRenderWindowInteractor and currently the left mouse button 
enables the pick (vtkWorldPointPicker). However despite where the pointer is 
on the image the picked coordinates are displayed as [0.0, 0.0, 0.0]. This 
would indicate that mouse position is being ignored by the pick object 
despite the use of GetSelectionPoint(). Has anyone any ideas about how to 
solve this??
