If I recall, the objective was to determine if a newer version of the
(n)curses library fixed the problem.

The reason I suggested upgrading the OS, to say the 2.2 kernel (1999),
is because I think that it is the easiest way to test and resolve the
problem.

Just use an old 486 (or above) with 16M RAM and a network card. Then
install a 2.2 system (without X), compile TC and test applications.
This could be achieved in a couple of hours.

The alternative is to upgrade to a new (n)curses library, or have more
than one (n)curses library on the old system (is this possible ?). Since
these options may make you system un-usable, it will require some test
system.
This option would require a lot more work.

Well here the reasons.

First of all, the people who worked on that portion of the TC Run-Time
are no longer active contributors to TC. Some are not even on TC mailing 
list.

Personally I'm not very familiar with the (n)curses library, or
terminals in general. And any information terminals is very hard to find.

In an attempt to isolate the problem, I've compiled and run some test 
programs using TC version 0.55 and the current CVS version. Both using 
ncurses version 5. While both versions run, the TC 0.55 version seams 
more stable, as it can be used with different TERM settings.

A lot of changes have been made to the curses section of the run-time 
since between 0.55 and 0.62, so it may take some time to try to isolate 
the problem(s).
