some more info.
 I havu put more printing into G4ExcitationHandler,
 now the test12 output

Comment 1 Hans-Peter.Wellisch 2001-10-15 03:18:59 CEST 
I see, this was fixed, but if you still get these gammes in the tracking
aparently the fix was only partly effective.
I'll fix again for the next release. (This means that the warning stays, but
the photon is erased and deleted.)
