Just the sort of cool sort of tools that make LC so much fun. But you need to
be careful in the case where controls may have behavior pathNames that call out
to more than one stack. You need to make sure that the behavior does indeed
reference the deleted ("oldStackName") before it replaces with the new one.

Subject: Reassigning stack names in behavior references
Behaviors are very useful. Scott Rossi gave an excellent presentation on them
at
the recent conference.
One thing that sometimes trips me up - I’ll assign a behavior to a bunch of
controls then I’ll re-name the stack that contains the original behavior
button.
Dumb :( because the controls can’t find the original reference button.
If you ever find yourself in that situation, here’s a script to rename the
referenced stack names in one shot.
on updateBehaviorStackNames oldStackName
-- If you change the name of the stack that owns a behavior button, then all
controls that have that behavior would fail to invoke it.
-- Use this handler to change the referenced stack in card controls that
have
behaviors.
-- It will replace the old stackname reference with the new stackname
if oldStackName is empty then
beep
answer error "Please pass old stack name."
end if
repeat with x = 1 to the number of controls
set the cursor to busy
put the behavior of control x into cBehavior
if cBehavior is empty then next repeat
replace oldStackName with the short name of this stack in cBehavior
set the behavior of control x to cBehavior
end repeat
end updateBehaviorStackNames
