I was asking for the purposes of managing pending messages. I have a
screen that "lights" a series of circles on the screen. There is a "new
game" button that brings up a "are you sure you want to start a new game?"
dialog. I wanted to pause and resume the "LightNextCircle" message. I did
finally create a SuspendPendingMessages and a ResumePendingMessages handler
for this purpose that I call on suspendStack and resumeStack, which works
fine. It goes through the pending messages, saves them, and figure out how
much time each has. When they are resumed, they are put back with the
remaining time left.
It was my understanding that "this stack" will return the name of the
top-most editable stack, so it would not return the modal dialog. I just
created a test, and it does:
"this stack" on an object in the modal dialog stack returns the modal
dialog stack (as in "close this stack"), but in a message sent to the
underlying stack, "this stack" returns the underlying stack.
I created a stack "Main Stack" with a button:
on mouseUp
send CheckThisStack to me in 2 seconds
modal stack "Modal Dialog Stack"
end mouseUp
on CheckThisStack
answer the name of this stack
end CheckThisStack
The modal stack "Modal Dialog Stack" comes up. and then the answer dialog
comes up with 'stack "Main Stack"' as the value of this stack, and not
'stack "Modal Dialog Stack"'

This is an interesting question; given that modal dialogs block the flow
of the script that opened it this rarely comes up.
Is this for managing pending messages?
You should find that "this stack" refers to the modal stack, so a script
that asks "if the mode of this stack is 5 then" should do what you need.
Can anyone think of a case where "this stack" would not return the modal
stack currently open?
