Hi Homer,
Where does your input generator file come from? Is there a chance it is sick?
Why don't you send me a copy and I can try it here. Have you run single pions,
electrons and muons through NBeam?
You should subscribe to the lcd-sim mailing list so others can be aware of
pitfalls and solutions...
