Hello Duncan,

Some of what you have written is over my head, but I want to fix this problem, 
so I will do my best to understand what you are writing about.

I found that when composing a message, under the tab, "More Headers", one can 
specify whether to "Add "Message-Id header" or not. This apparently changes 
the message ID. With it checked the message ID is as you described above with 
a date/time stamp and the domain name that is entered by the user in 
the "Posting Profile" box. However, if it is unchecked, the message ID is 
entirely different. Here is an example from one of my test posts: 
<address@hidden>

There is another option there, but I don't know what it 
does: "Add "user-Agent" header".

I did some tinkering based on your suggestion to open the reply in a text 
editor and modify the references header. Never having bothered to really look 
at this stuff, I learned that some of that information actually means 
something!

Here is what I did: I found a reply from Free Agent that was maybe 4 or 5 
replies into the thread and was one that I was not able to reply to in Pan. I 
then eliminated all of the references except the first and the last and tried 
to reply to it in Pan. The message was posted to the n/g and it might even 
have ended up in the correct place in the thread.

So, what do I do now? Apparently my ISP doesn't like it when Pan has more than 
two references in the header while who knows how many in Free Agent are 
acceptable. So, I can fool my ISP's filter by changing the reference 
information in the header. I don't know if that will always allow a replied 
message to be placed in the proper location in a thread, and it is, of course 
a rather unwieldy way to post to the Usenet.

Hopefully I will have some time tomorrow to do some more tinkering. And maybe 
I have provided you with some useful information. I'm sorry if I've done a 
poor job of describing what I did, but much of this is new to me.

Thanks for your initial help.
Harry
