topLevel vs. open stack

[Dan Shafer]

If I'm reading the docs correctly, topLevel should close a stack if 
it's open and then re-open it in an editable window UNLESS it is 
already open in an editable window, in which case it should merely make 
it the current stack. But there appears to me to be some subtle 
difference between sending "open" to a closed stack and sending 
"topLevel" to a closed stack.

Here's my basic demonstration.

Stack is open. It has a field 1 and a button. The button has a script 
that looks like this:

on mouseUp
   lock screen
   lock messages
   select field 1 of this stack
   copy
   topLevel stack "foo"
   paste
   unlock messages
   unlock screen
end mouseUp

Clicking the button brings up stack "foo" in an editable window as 
documented but the paste never happens.

Simply change "topLevel" to "open" and the script works as expected.

If I begin with both stacks open, the result is identical.

So two questions arise:

1. How if at all can I copy and paste objects between two open stacks?

2. Why does topLevel behave differently from open and from the way it 
seems to be documented?
