None no count for n(B,alpha)Li reaction using

Dear All,

After Update my G4 version from G4.5.2 to G4.6.1 There are somethings strange in my program. I use as an example to track particles in region I am interested in. There is a brief code below...


ExN07StackingAction::ClassifyNewTrack(const G4Track * aTrack)
  G4TouchableHistory* theTouchable
   = (G4TouchableHistory*)(aTrack->GetTouchable());
    G4VPhysicalVolume* calPhys  = theTouchable->GetVolume(0);


                     .............  .........
    return fUrgent;


I shoot thermal neutrons in the BF3 gas chamber.. There are n(B,alpha)Li reactions ( use command /tracking/verbose 2 ). But I don't know why there is no count for the ExN07StackingAction code.. Another physics process is ok using ExN07StackingAction to count particles.

First time, I use G4.5.2 there are no problem in this case, but after I update to G4.6.1 there are lots of problem

Could anyone help me ? Thank you ...
