I have another answer I can live with a little easier. I wrote another
proof of concept script wherein the MainWindow is kept as mentioned before.
It looks like I can create and destroy Toplevel windows as I need to,
while keeping the MainWindow withdrawn.

This works without getting a segmentation fault:

sub service_for_mw_button_press { my ($mw) = shift; my $top_level = $mw->Toplevel

and then later, when I no longer need the $top_level,

$top_level->destroy; undef($top_level); $mw->deiconify; $mw_raise;

This idea, plus a redesign to make the real program an event driven
design from the beginning, should do the job. Thanks for all of your
