Can you try the reply again and I'll let you know if I get it.

public-midrange-l=Zwy7GipZuJhWk0Htik3J/w@gmane.org but the e-mail came to
me.

Jim, there are a few things that may be of assistance to you. Some of your
comments later in the thread make me wonder if they might be helpful or not.
Please reply with a phone number so we can chat about it.
