After pressing "r" and using the HighlightInteractorStyle to do selection, seems always all vertexes (50 cells and 50 points) were selected and highlighted, no matter how I select an area. Is it the expected behavior or possible bug in the example or vtk? I am using vtk 6.1. Any hint or help will be greatly appreciated.<span class=""><font color="#888888"><br>

This seems to point to a bug in vtkExtractPolyDataGeometry, as I believe their calls are supposed to be the same. I'm not sure if I'll have a chance to dig into it.<br>
