Invisible clone?

[Richard Gaskin]

I could have sworn this worked in an earlier version, but darned if I 
can do this gracefully now:

I have an app that makes new documents by cloning a substack.  What I'd 
like to do is set the visible of the substack to false, clone it 
invisibly, modify its rect, title, and some other properties, then show 
it when it's ready.

But try as I might I keep getting the clone visible as soon as it's created.

What's the trick?
