    I am having a problem with twm on an Ardent Titan II.  The first
time I bring up a user-defined menu, things work as expected.  The
overlay box is produced and filled with labels, each indicating the
appropriate window manager function.  The second and all subsequent
tries at the window produce the overlay box empty (meaning that there
are no little labels).  The menu will function correctly, ie. if you
select a ``label'' then release the button, the function is executed;
but, at no time is the text of the label visible.  So, you must have a
very good memory in order to fully use the menus. :-)
    Now that you think you have it figured out, there are two more
intersting points.  The TWM window menu always works correctly: labels
and all.  Furthermore, if you select the ``source .twmrc'' function
to reload the data structures, the labels will again appear the first
time (as before).  Very strange...
    I know that we could use awm instead, but my userbase has become
very accustomed to twm on the Sun-4's.  Those that have played with
awm, myself included, have come to the conclusion that twm is more
versatile and perhaps even a shade faster. (Thank you, Tom!)  Needless
to say, switching to awm/uwm/wm is not a viable option.
    I have hunted through the code for almost a month now, and I think
it's time to admit defeat.  The code runs flaawlessly on the Sun's, or
at least it has me fooled, and runs beautifully on the Ardent's, except
for the one flaw mentioned.  Has anyone else ever seen this problem?
Does anyone have any ideas?  (Tom are you listening?)

    Many thanks,
                    bert
