The following command in 10.7.p2 /process/optical/setTrackSecondariesFirst Cerenkov 0 sets G4OpticalParameters::cerenkovStackPhotons instead of cerenkovTrackSecondariesFirst. Can you, please, fix? The new command /process/optical/cerenkov/setTrackSecondariesFirst false works ok.
Thanks Ivana, this is now fixed for the next patch release.
