Greg,

Do you think I'm crazy? I sure only do NODEFAULT when I don't want it to happen. But the point is, it doesn't work.

To make sure I put

LPARAMETERS nButton, nShift, nXCoord, nYCoord
this.AddProperty('lOkToProceed',.t.) 
IF thisform.lMadeChanges and thisform.AskToSave() = 2
   =MESSAGEBOX('Here')
   this.lOkToProceed = .f.
   NODEFAULT
   RETURN 
ENDIF    

The click is ignored in both cases (here and not here).
