Description Sebastian Heil 2013-12-20 01:46:10 CET 
Hi,

in the previous version, calling

G4long myseed = time(NULL);
CLHEP::HepRandom::setTheSeed(myseed);

in my main() did the trick to get independent runs.
Now in version 10 it seems to have no effect.
Since I can't find any hint that there has been a change to that part, I assume this is not working as intended.

Best regards,
Sebastian

Please refer to the migration guide.
You should not directly use CLHEP::Random anymore.

No idea how I could have missed this part multiple times. It's working now.
Thanks very much.
