I tried a number of variation with ID, the long ID, the owner, the 
effective filename, but none of these properties or other prevarications 
helped.

Apparently the "cohesion" or "binding" between

stack "mysubstack"  of stack "mystack"

is not strong enough and we would maybe need a new syntax like "delete 
substack "x" of stack "y".

Stack "stack components" that contains the delete button is itself a 
substack of "mctools" and therefore at first comes across the identical 
substack in "mctools" and then deletes both identical substacks.

The only solution I have found is to move stack "stack components" out 
of  "mctools" and transform it to become an individual mainstack. Now 
only the intended substack is being deleted and the identical substack 
in "mctools" remains untouched.

The reason why the message box is also a possibility like I reported 
above - although it is also a substack of "mctools" - seems to be that 
"stack components" is opened as a palette, whereas msg is opened as 
"modeless"(?).
