Problem is that in our tests your problem does not seen. To identify the
problem one can do following:

1) Run your application in your standard mode - in case of problem print
out Event ID = Nevent.

2) In UserEventAction at the Start of Event actions add if statement, and
if the number is Nevent-1 add following line:

 (G4UImanager::GetUIpointer())->ApplyCommand("/tracking/verbose 2");

of course, do not forget

#include "G4UImanager.hh"

3) Run your application again - you will see the detailed history of this
event and will be able to identify a problem in more details. Send output 
to me, for example.
