Object paths?

Not quite: the defaultStack is the stack in the current message path, 
but can be set to point to any other stack to allow incomplete 
references to objects in that stack.

For example, when a button is clicked, the defaultStack is the stack in 
which the button object is located, but if you set the defaultStack to 
another and ask for "the name of btn 1", what you'll get is the name of 
the first button in that other stack.

Try this - make a new stack, add a button with this script:

on mouseUp
   put the defaultStack &cr& the topstack
end mouseUp

Then set the style of the stack to palette, create another new stack as 
toplevel, and click the button in the palette stack.

What you should see is line 1 of the message box will contain the name 
of the palette stack in which the button was clicked, but line 2 will 
contain the name of the second, toplevel, stack.
