Also, (though I wouldn't think it's the cause of the problem), you  
don't need to open the stack, this should work:
	
   set the customproperties["allDataProps"] of stack whichFile \
       to the customproperties["allDataProps"] of stack "dataTemplate"
   save stack whichFile
   delete stack whichFile -- does not delete! simply removes from  
memory.

Best,

Mark
