We may have to resort to that Peter, but I am up to it in a different pool of aligators ATM. Mechanical stuff on this Sheldon. And a wife in the end months/weeks of COPD. Thats taking some of my working time. One of the hazards of outliving ones enemies. :) Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
