Msaccess Enhanced Message Box - Office update issue

Thanks for your responses.

I added the following code as a workaround:

' cleanup
    Set F = Nothing

'
    ' Fix to ensure form closes after user response
    '
    Dim I As Integer
    For I = Forms.Count - 1 To 0 Step -1
        If Forms(I).Name = "frmEnhancedMessageBoxFormDialog" Then
            DoCmd.Close acForm, Forms(I).Name, acSaveNo
        End If
    Next I
