After a little research (prompted by several polite pmails) I find that
what I thought was a problem realy isn't a problem.  First, the threads I've
seen broken were not because of the "Re:" in the Subject line.  But most
important the email clients are in fact ignoring the Re:, it is being added
by the email software (including mine using Gmail) and apparently Yahoo mail
and I assume others. BUT, if no other changes to the Subject line, the
thread is NOT broken.  Sorry for the earlier post, a little more research on
my part would have avoided the confusion I might have caused.
Now back to our regular programming?
