Now that I'm in the spotlight I can't seem to find the message I was
referring to in the archives; I sure hope I didn't misquote anyone (i.e.
Jim).

Unfortunately, I don't have an answer to your question. I still believe I
am correct, but cannot tell you, technically, why. I have some theories,
but I don't want to cloud the issue anymore with my hypotheses.

Let's hope someone who does know chimes in.
