...just a note jc ...www.trigeminal.com is loaded with replication info, code, and tools ...HTH :) William Hindman "You know the world is going crazy when the best rapper is a white guy, the best golfer is a black guy, The Swiss hold the America's Cup, France is accusing the US of arrogance, and Germany doesn't want to go to war." ----- Original Message ----- From: "John W.
