Yes, that's one of the things I've enjoyed about using stack files for 
storage, the engine's automatic safe-write procedure that makes a backup 
of the old file before writing the new one.

Of course we could script our own routines to do that, but I don't mind 
a little convenience now and then.

Imagine how much worse those users would be without that safe-write.

Did you ever find out why the engine was having difficulty writing those 

What did "the result" show?

Beyond the implications for end-users is for all of us: if there's a bug 
that prevents writing stack files under certain circumstances, it will 
prevent us from using LiveCode under those circumstances.
