Mr. Vigg, it seems that Mr. Grubb does not have much tolerance for all this. I'm really sorry to both of you, but I couldn't resist the pun. From a position without ego, as I have no hamster in this fight: I think you've both heard each other's points, now it is up to each of you to consider whether or not the other might have some valid reasoning. Instead of considering this as an argument, perhaps you should think about it as a collaborative session of problem solving. It doesn't matter so much who is right, as long as the right answer is found. And yes, I realize I probably shouldn't stick my nose in the middle of this... But I really wanted to make a tolerance pun.
