Hi,

Addition of the following Macros in the ThisWorkbook Code Module may help you:
Private Sub Workbook_Activate()
  Application.ExecuteExcel4Macro "show.toolbar(""ribbon"",false)"
End Sub

Private Sub Workbook_Deactivate()
  Application.ExecuteExcel4Macro "show.toolbar(""ribbon"",true)"
End Sub

Private Sub Workbook_BeforeClose(Cancel As Boolean)
  Application.ExecuteExcel4Macro "show.toolbar(""ribbon"",true)"
End Sub
