I'm using Thunderbird 14 on Linux, and I'd love help in diagnosing why
some messages get properly threaded, and some do not.  For example, I've
seen several of your replies (not a very big fraction) apparently start
new threads.  And I've seen many other messages which didn't get in the
proper place in the thread, appearing at the same level as the message
they were replies to.

I will be upgrading to latest Thunderbird, but I'm planning on
installing a new Linux on a new hard disk, and haven't really gotten
started yet.

His first message showed one line, typed in the interpreter, with no
clear statement of environment or problem.  However, the statement did
mention the input function.  I'd have disbelieved it except that...

His second message specifically changes to input.  Here it is again, for
our confusion:

"""Didnt show up at first. Result was an eof error (using input not raw_input)
Found with interactive interpreter
"""

I would have been replying to that one, except that it apparently
started a new thread, as did his third message.  That third one went
back to using raw_input, but it was a reply to my message stating the
hazards of input on Python 2.x
