Save stack as...

[Ken Ray]

Shari,

You're right... you can't get the script of a stack or even check the custom
properties of a closed stack without opening it. Best approach is to lock
messages, open the stack invisibly, get the script, close it (making sure
its destroystack and destroywindow are true), and then run the rest of your
script.
