        Case Else
          'Do Nothing
      End Select
      On Error GoTo 0
      'Get next linked story (if any)

    Loop Until rngStory Is Nothing
  Next
lbl_Exit:
  Exit Sub
End Sub

Hi,
the code works fine, but If I am in the printView View the code changes to Draftview during execution and back to printView afterwards. How can I prevent this?

best regards,

Andreas
