reported on Hypernews Optical Processes Forum, thread #334.
o Refashioned code in the case of type 'dielectric_dielect'.
+ Transportation:
o Fix to G4Transportation to properly update the step flag which
identifies the last step in a volume (applies for linear steps only,
i.e. no field). Partially addressing problem report #1032.
o Run:
---
+ Corrected printing of number of events processed on run abortion.
+ Fixed definition of path for Windows in G4RunManager for random seeds
directory: use '\' instead of '/' and suitable system command.
