If you put this into the stack script does it do what you want?
on errorDialog pError
put pError
end errorDialog

Many thanks to Craig and Jacqueline for their suggestions. I had never
used the “errorMode,” but could not get it to work. The “suspend errors”
button (or menu command) seems to do what I want, but with a bad bug (see
below). The “suspend messages” button (or menu command) does work as
Jacques suggested.
I created a test stack that has one button with this script:
on mouseEnter
put random(1000)
get missingHandler()
end mouseEnter
A. With neither “suspend messages” nor “suspend errors” in effect, when
the mouse enters the button, the message box gets a number and an error is
triggered by line 2’s missing handler.
B. If I “set the errormode to quiet”, the same thing happens (so this did
not suppress the error on line 2).
C. If I choose “Suspend messages”, no number is put and no error is
triggered. As expected!
D. If (with “Suspend messages” turned off) I choose “Suspend errors,” the
number is put but no error is triggered. As expected!
But: I can execute case D once, but the stack then becomes unresponsive.
If the mouse reenters the button, no number is put; and other controls will
not execute their scripts either. It is as if having suspended errors
successfully once, all messages get suspended, and nothing works until I
restart.
So I think “Suspend messages” will do what I want, but I would like to
understand why “Suspend errors” (which would be preferable for my purposes,
since it allows innocent messages to proceed) doesn’t seem to operate
correctly.

Does the "lock messages" icon in the toolbar at the top do it?

I am wondering if any other users have faced or solved this problem:
I have over the years constantly revised some basic tools I use to create
and edit stacks where I store substantive information of various kinds
(tables, images, text). The scripts of those substantive stacks send
messages to be handled by my “tool” stack; but as a result of later
revisions of my tool stack some of those handlers have disappeared. So if
I simply want to inspect old substantive stacks I am stymied by error messages.
One solution would be an ability to lock messages persistently, but I do
not see a way to do this. I can imagine a workaround that would lock
messages, then copy the content but not the scripts of the objects in my
substantive stack to some new stack where I could study them.
But I wonder if someone has already done this or has a different idea.
Many thanks.
