Agent putting Responses in wrong thread.

[Martin Harran]

My installation of Agent is increasingly adding responses to posts
into the wrong thread. For example, I replied a couple of days ago to
a message in a thread started just two weeks ago but my posts and
responses to it are buried in an old thread where the last post was
2008!

I don't think it's a Headers issue as when I check the headers in
Agent, the correct Subject is shown. Also, when I click on the last
Reference Message ID, it takes me to the post to which I am replying,
in the correct thread.

In order to view responses to my post, I have had to create a "Last 3
Days" filter. That filter shows the response in the correct thread!

This is only happening in Agent, the correct threads are maintained in
Google Groups.

I've tried Repairing the Foder but it has had no impact.

This is a known problem when Agent has lots of headers in the group.
For previous discussions, search this group for the phrase
"hash collision":
URL: <https://groups.google.com/g/alt.usenet.offline-reader.forte-agent/search?q=%22hash%20collision%22>

For example, see this discussion from December 1997:
Subject: Mis-threaded messages
URL: <https://groups.google.com/g/alt.usenet.offline-reader.forte-agent/c/ZUnJCJx2hFg/m/gw4M2npWMYwJ>


For a table showing the probability of mis-threading vs. the number
of headers in the group, see this post from May 1997.
To read the table you may need to use a fixed-pitch font. E.g., copy
the text from Google Groups and paste into a text editor that is using
a fixed-pitch font.

To clarify...

This is the probability that at least one mis-threading will
occur somewhere in the group.

This is not the probability that any given message will be
mis-threaded.

Seems like no real answer to this unless I delete old posts which I
don't really want to do :(

User-Agent: ForteAgent/8.00.32.1272

Or, move old posts into a sub-folder (or multiple sub-folders
indexed by year).

If you use Find Global, it has an option “Include sub-folders”.

That is a very useful solution, thank you for that.

If you happen to create a new posting with the same subject of an
existing older posting, your new posting will be found "in the thread"
of the older one.
This can be avoided by making the new subject unique, like eg by
including yy-mm-dd-hh-mm.

H.

You can also avoid this case by turning _off_ “Enable threading by
subject”, at:

[Agent 1.7-1.93] Options >> General Preferences >> Message List
[Agent 2.00] Options >> General Preferences >> Display >> Message List Pane
[Agent 3.0-8.00] Tools >> Options >> Display >> Message List Pane

After you turn this off, it may not take effect immediately. To make
it take effect in a folder, change the folder's message list sort and
then change it back.


it is still a good idea to make the new subject unique, because other
readers of your post may have “threading by subject” enabled.

Yes, I'm aware of that; it's not the sissue here, it's what Ralph
identified - too many headers in a group.
