Hello Thomas,

Strange. Do you have:

theTrack->SetTrackStatus(fStopAndKill);

in your SteppingAction::UserSteppingAction?

> Is the Track ID changed after reflection?

No!

The G4OpBoundaryProcess prints and then returns (no action):

        if (aTrack.GetStepLength()<=kCarTolerance/2){
                theStatus = StepTooSmall;
                if ( verboseLevel > 0) BoundaryProcessVerbose();
                return G4VDiscreteProcess::PostStepDoIt(aTrack, aStep);
        }

You need to debug where/why the track stops. Do you have a SteppingAction? If not, write one and make it print something.

Do you have access to the Geant4 source. Debug:
