Basic concept:
Add a property to the form named OLastFocusControl.
In each type of control's GotFocus (you are subclassing controls, of course..) --
(1) IF VARTYPE(Thisform.OLastFocusControl)="O", do your calculations.
(2) Then set Thisform.oLastFocusControl = THIS if the control is a data control or = NULL if it is a non-data control (i.e., command button).

BTW, I rely on this basic approach for my validation -- because sometimes my validation depends on not only which control the user just came from, but also which control has focus now. This approach also makes it easy for me to issue WAIT WIND NOWAIT warnings for invalid entries while letting the user continue to move freely around the form, and then hard-trap the error and display a dialog box if the user attempts to save a record with invalid data.
