Let's say a user creates a stack from one of my templates, then later in

this? Or should I construct a routine to parse the file name out and set
the name to correct for this?
What happened when you tried it?
It's a quick test:
1. Make a stack
2. Save it
3. In the Finder/Explorer, change the name of the file
4. Save it again
When I tested it here I got the result I expected given that the stack's
understanding of its file name is what's stored in its fileName property
which is initialized when the stack opens:
If the name of a stack file is changed while the stack is open, that
change is ignored when the engine saves, writing it instead to the name
as it last understood it to be.
Where things can go wonky is when a user changes the name of a folder in
that path - then the engine won't be able to write to the original
filename because it can't find the path to do it.
When file I/O errors happen you can check the sysError function for
details. The function isn't all that helpful in itself, returning only
the system error ID for what happened, but if you keep a table of those
handy you can write meaningful messages to users or at the very least
include the result from sysError in your error dialogs so if your user
calls for support you can look it up then.
