Update:

I just got an OG dialog box that shows me OG is indeed trying to do 'autosave' (is this same as Backup? - would seem to be).

What Caused Dialog To Appear:
Without quitting OG, I had used Finder to create a Copy of my then open .graffle, and upon returning to OG and bit later going to Save the still open graffle, I got this dialog box:

Dialog:
-------------------
The document "CB3-FOLDERS-FlowDiagrams.graffle" could not be autosaved. The file has been changed by another application.

Click Save Anyway to keep your changes ...
or Click Revert to keep the changes from ...
--------------------

As I noted initially, the General Preferences for my OG (latest version) do not show any control viz. Backup, or AutoSave, etc.

Thanks.
