[vtkusers] vtkPropPicker bug/problem?

[Dimitris Agrafiotis]

Dear All

This is the second time am sending this. I have two actors and I am 
using vtkPropPicker (h/w picker) to pick one of the two (the other is 
set PickableOff) (I am using the GetPickPosition() function to get the 
picked point). However it seems the PickableOff Actor is also picked 
(when it is in front). 

!!!
I have tried PickProp() with a vtkPropCollection which is supposed to 
check only the props included in the collection and it doesn't work.  
!!!

Any advise?????

Thanks in advance
Dimitris
