Hi there Bruce,
Am I correct in my recollection that you were doing the numbers on the P19MX a while back? Now it is the I-20. Are both of these configurations giving you a hard time?

Couldn't resist. I've exchanged posts with you before and "am stepping out on the limb a bit". Hope you take it as a little humor, certainly nothing else intended. :-)
