Question Problem in MuIoni? 

Forum: Event and Track Management
Date: 06 Oct, 2003
From: V. Grabski <grabski@fisica.unam.mx>

Hello, I have got infinite loop in my program (which was OK with the old version geant4.5.2.p01)with the new version (geant4.5.2.p02).After installation i have got the message that there can be an error, but I have looked the log file and didn't fined any error?? Seems that there is a problem in MuIoni - process? or any idea? Thanks for advance, Varlen
