@Richard,
That is precisely what I saw when I did my test.  (And DG3 was in a
different stack.)
I tried manually replacing the old button with one in the stack and that
completely broke the DG.

@Bob
Another option to get script in front of the library would be to set the
script of:
button id 1005 of stack "revDataGridLibrary"
That still wouldn't save with the stack though.
