Thank you for the reply.
No, this is very simple geometry for debugging - only 1 target and 1 Crystall. So, there is no possibility of another "Crystall" volume standing next to it.
I switch on verbose 1 and here are details of 2 cases I have

Looks like if interaction is happening in the Crystall step will still satisfy condition

 if (thePrePoint ->GetStepStatus()==fGeomBoundary && postname == "Crystall")

Does the prestep Status is still fGeomBoundary after transpostation has occured from another volume?
