Close and Remove stack from memory

[Stephen Barncard]

Hello, Friends,

I'm having trouble with trying to 'Close and Remove Stack from 
Memory' a stack window in a script while working in the IDE. No 
matter if I use the 'destroy' properties in any configuration - I 
still get the 'conflict' dialog from the IDE. Is there an incantation 
- a window type or whatever - to fix this? Eric, you've had to deal 
with this in your Backup plugin....

I'm saving a preferences stack to a different file name in a 
different area to be used as a clone later for 'first time 
installation' of the prefs file.

I want it to be saved and then have the copy go away. But the memory 
image of the backup stays around, and if I open the prefs file, the 
IDE complains.

One can do this in the Application Browser -  how does one do this in a script?

thanks
