[vtkusers] vtkCellPicker

[David J. Netherway]

This time I have actually added the attachment.

Here is a crude example of a problem with using the cellPicker and

The work around by Patrick de Koning works, I have yet to download and try
the latest version of vtk as suggested by Charles Law.

Thanks to all respondents, David
