James,
As Hilmar explained just turn on buffering once at start (and at the very beginning, ie: directly in DE or load method). If you don't do that early enough you might cause the situation you describe (like Fox2x behavior-God I had to check it and act accordingly in those days).
With buffering set to 5, you may choose to save/revert all or single record changes using the parameters.
If you would do it single record wise buffering 3 is an option but hard to control unintentional implicit tableupdates.

PS: Don't forget, if you don't control it with functions like oldval(),curval() and have force parameter set to .T. in tableupdate, if two edits the same record then it's a "last write wins" implementation.
