I know Ralph requested email on the subject, but I feel compelled to
post a note here.  I have also seen this problem, starting with version
4.1 of the tn3270 program.  I hacked together a really gross fix for
our site and contacted Greg Minshall about this problem.  He replied
that version 4.1.1 had fixed some problems with CICS screens.  I
obtained a copy of version 4.1.1, but it still didn't work correctly.
I sent Greg copies of some network traces that show the traffic between
the tn3270 host and the IBM system, in hopes that he might be able to
duplicate the problem.

I would like to see these problems fixed by Greg or someone in his
group.  My patchs seem to work, but I don't trust them for general
distribution, since my understanding of how the tn3270 package works is
incomplete.

I would encourage anyone who is having similar problems either post
about them here or send a note to Ralph (rwc@mhinfo.UUCP), who has
volunteered to collect them and then post a summary to the net.

Let me end by saying I do appreciate all the work that Greg Minshall
has done to provide this valuable package.  I just hope that we can get
the last few quirks taken care of.
