[vtkusers] vtkPropPicker not picking

[Will Schroeder]

Hi Edi-

There is a potential problem to be aware of. That is, some PC boards
do not support hardware OpenGL picking. (This is true of my Erasor X
board, for example.) It seems that many of these commodity boards 
test by running Quake or Doom, and if they work the board is shipped.

Anyway, what kind of board do you have, what system, etc?
