just a moderator's salute here to Stu_Strib and jamsjr44. these are two members who have disagreed in the past. in this thread they show a perfect example of how we can vociferously disagree in a mature way. these kind of supported respectful arguments are instructive and valuable to our forum. there is a wry sense of humour and plenty of evidence that they read eachother's comments carefully. respect to you both and ... more of the same.
