dudley, don't be discouraged - downvotes don't matter, and don't mean much. People ++ and -- based on all kinds of reasons. My answer to yours is downvoted lower than your original question right now - but who cares?

If you are frustrated at the lack of response, then maybe you are finding issues in areas where people are just not that knowledgeable. I certainly couldn't answer it, and there are many more knowledgeable and helpful folks here than I. Maybe even you're the first to find this problem. Maybe the folks that really know this only log on at other times of the day.

Someone may yet provide an answer to your question.
