asterisk users - Jul 2005 - Queue Statistics on 1.0.7

I'm running v1.0.7 on Gentoo. When I execute show queue {queue_name}  
it ALWAYS shows zeros (0) for all the statistics, when in fact, there  
have been calls and there should be some statistics available about  
the queue performance. Any clues as to why this may be happening?

Thanks,
Waldo
