2) If the defaultStack is changed in a handler called from another

I think (2) is definitely not wanted. If the locality of a change to
the defaultStack propagates back to callers, then the callers loose
control and knowledge of what they are actually acting on.
Note that this is *not* the current behavior. Changing the defaultStack
in a callee will propagate the change back up to the caller.
i.e.
on mouseUp
set the defaultStack to "Foo"
changeDefaultStackInCallee
answer the defaultStack -- will be "Bar"
end mouseUp
on changeDefaultStackInCallee
set the defaultStack to "Bar"
end changeDefaultStackInCallee
Here you'll get 'Bar' in the answer dialog.
Warmest Regards,
Mark.
