When does a Stack Actually Die in the IDE???

stackIsOpen2 takes the long id of an object, gets the short name of
the stack the object is in, and then checks whether or not it's among
the lines of the openStacks - which is a list of the short names of
all currently open stacks, not their file names.
It seems to work perfectly well, here ( I assume the listing below is
not your actual script, there are typos ).
Best,
Mark
