> Doug, do you perhaps need new glasses? Of course I do, Eric. I always need new glasses as they never can get them ground quite properly (combination of severe nearsightedness and astigmatism with being crosseyed means perfectly ground lenses are rare.) A little closer to your old form which I loved so much. I must say I am amazed at the defensive reactions to a little gentle ribbing (at least it would have been condsidered such just a few years ago). Preaching to the choir a little, aren't we? That's okay, the old members of the choir still find the sermon interesting when couched in new terms. No, I'm not trying to provoke anything further as all of this has been quite silly (which I assumed everyone knew from the outset; it was supposed to be silly and has certainly lived up to the expectation). Do have to put an edge to the "Eric baiting" skills every once in a while, though. I've gotten too many valuable answers in detail on difficult problems with the technique, when direct questions failed, to give it up entirely.
