I (think) I have solved my "random and non-reproducible" crash on quit
syndrome. It seems to have something to do with the menubar, and with
closing and opening stacks. The problem was triggered in my app after
switching between the "normal" and "presentation"modes in which the menubar
is hidden and all stacks closed and re-decorated, and then re-opened. I
found an inconsistency in the closing/opening sequence in my script and when
I sorted that out, the problem seemed to go away. It is still odd to me that
the problem didn't manifest itself at the time I initiated the switch mode
command, but only later when I quit. There was a residual problem in turning
tooltips back on after leaving the presenation mode, which caused a crash
the first time a tooltip  came up,and this seems to have been resolved too.
Something I obviously don't understand about memory, but I am relieved that
I haven't been able to re-create the crash since making that simple change.

Thanks to those who offered suggestions
