[AccessD] Key Preview Problem

Dear List:

I have a tab form with four tabs.  I want to set the focus in each tab 
by pressing the functions keys F5, F6, F7, F8.  The KeyDown event is coded:

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)

    Select Case KeyCode
        Case 116
            Me.pgOrderNumber.SetFocus
            KeyCode = 0
        Case 117
            Me.pgReceiving.SetFocus
            KeyCode = 0
        Case 118
            Me.pgProcessing.SetFocus
            KeyCode = 0
        Case 119
            Me.pgShipping.SetFocus
            KeyCode = 0
    End Select
   
End Sub

The first time I press one of the four function keys it works.  Then, it 
quits.  (Like if I press F7 the first time is sets the focus to 
pgProcessing, the second time it invokes the spell checker.)

Does anyone know why this would happen?
