ACCESS '02: How To: Make main window inaccessible ???

Access 2002 (XP)

I can make my user Forms "PopUp" and "Modal" which renders the main Access Window inaccessible, but how do I get the main (parent) window off the screen so the user can't even see it? What can I put in the Form Open event?

Private Sub Form_Open(Cancel As Integer)
    
    'Minimize or hide the main window
    How do I do this???
    
End Sub

Thank you for any and all comments, suggestions, and assistance.
