Hi Zach,

Sorry, the Application Developers Manual has an outdated name for the class G4StepLimiterBuilder!

The correct names is: G4StepLimiterPhysics

Please, see the actual code in basic/B2/B2a or B2b and the code at:

http://www-geant4.kek.jp/lxr/source/physics_lists/constructors/limiters/src/G4StepLimiterPhysics.cc#L76

Here, you'll see that the max. time is applied to all neutral particles including optical photons.

However, if your photon tracking gets stuck (somewhere) that doesn't mean that the propagation time increases. For example, an infinite number of infinite small steps. So, you may still find that after applying the G4UserLimits your program still hangs. Ideally, you can find out what actually happens, where and why?
