Ian replied to me privately indicating that he was hoping that someone more
familier with the code this tweak is affecting would have a chance to review
it.
So .. is it possible to get some feedback from those more qualified to
comment .. if you think I'm off my rocker suggesting such a change; I'd love
to hear about it; hopefully with an explanation that I can respond to /
understand...
Thanks everyone!!
