Ok, I see better what you're up to...probably you want to put all your code this elsewhere, in either the form's Close button (assuming you have one) and/or in the Queryunload, where in either case use the Nodefault with your code.

Form Lostfocus or Deactivate are not best-suited for this, I think...
