No, you just turn buffering on at the beginning, and then keep it on all the time.

When the user wants to save, you try a TableUpdate() (and when this returns .F., get information about the error with function aerror(), and show this to the user).

When the user wants to cancel, you just do a TableRevert().

There is really no need to turn buffering on and off all the time.

I know how this works with turning buffering on/off for each record as I've been doing, but do not understand how I would do that it I only turn it off when the user is done with all records.

>>>I've been having problems from time to time with one form that uses buffering. The problem, which occurs very sporadically, is that sometimes, when one user is on the form, all other users who start up the form get stuck with the hour glass.

>>>The form is fairly simple, and allows for adding/editing some simple records. Buffering is turned on (see PROCs below) if either adding a new record or when an existing record is selected to edit. Buffering is turned off later, allowing the table to update or reverting. There is no use of LOCK, RLOCK, or UNLOCK,
