Updating stack without going to it

[Mark Swindell]

Can one make visible changes to a stack (change card, update field  
propeties) without actually going to the stack?

I have a situation where I'm trying to update a navigation stack  
(which is the mainstack) to reflect having selected any of multiple  
open substacks.  I'm using a resumeStack handler to accomplish  
this .  The problem is that I get into a recursive situation, as  
every time the resumeStack goes out and updates the navigationStack,  
it has to return to the substack and the resumeStack is called again,  
and around we go.

I know this should be simple, but I'm not getting it.

Thanks,

Mark
