Look, lots of people have given freely of their time, expertise and money to try to understand and solve a problem that's not their fault. Some of us have thousands invested in a company that, apparently, thinks it can bait and switch us with impunity.
Given the circumstances, it's not a straight line to the answer. We don't have the same testing facilities as the manufacturer. We have to do our best with what we have. The situation, unfortunately, is still evolving on a trial and error basis.
So I find it awfully insulting when someone drops by every couple hundred posts and ask us if we're done yet. That's why I gave you the response I did. Had it been a lighter thread, then I'm sure I would have responded differently or not at all. My apologies.
