Thanks for confirming.  We can develop a strategy for working around
this effect, so from my point of view, we can consider this matter
resolved.  I'm guessing that you feel the same way, but if not, I'm
happy to help out in any way I can.

In any case, I do appreciate your efforts and the time you took to
write out the very helpful explanations you provided. __
