Ok, once more time, here's the fantastic Buffer() method:
* Save the current buffer
* Call from Save() and AddNew()

* We need to make sure the hierarchy is not coming from a Valid() event
* because this will generate an error
* In Visual FoxPro 5, we are not allowed to call SetFocus() from a Valid() event
LOCAL lcProgram,lnCompteur
lcProgram=PROGRAM(1)
lnCompteur=2
DO WHILE LEN(lcProgram)>0
   lcProgram=EVALUATE('PROGRAM('+ALLTRIM(STR(lnCompteur))+')')
   lnCompteur=lnCompteur+1
   IF UPPER(RIGHT(lcProgram,6))='.VALID'
      RETURN
   ENDIF
ENDDO

IF TYPE('_Screen.ActiveForm.ActiveControl')='O' 
   IF UPPER(_Screen.ActiveForm.ActiveControl.BaseClass)=='GRID'
      * Test if this is an active grid column
      IF _Screen.ActiveForm.ActiveControl.ActiveColumn<>0
         IF UPPER(EVAL('_Screen.ActiveForm.ActiveControl.Columns(_Screen.ActiveForm.ActiveControl.ActiveColumn).'+;
          TRIM(_Screen.ActiveForm.ActiveControl.Columns(_Screen.ActiveForm.ActiveControl.ActiveColumn).CurrentControl)+;
          '.BaseClass'))='OPTIONGROUP'
            _Screen.ActiveForm.ActiveControl.SetFocus()
            ELSE
            =EVAL('_Screen.ActiveForm.ActiveControl.Columns(_Screen.ActiveForm.ActiveControl.ActiveColumn).'+;
             TRIM(_Screen.ActiveForm.ActiveControl.Columns(_Screen.ActiveForm.ActiveControl.ActiveColumn).CurrentControl)+;
             '.SetFocus()')
         ENDIF
      ENDIF
      ELSE
      _Screen.ActiveForm.ActiveControl.SetFocus()
   ENDIF
ENDIF
