I guess after four years you won't have this question in mind still, so I just wanted to convert your comment into a complete answer, so that others have the answer a bit easier. The solution also works in Excel 2016.

Private Sub Workbook_Open()
    'MsgBox "Opened and disabled"
    Application.CellDragAndDrop = False
End Sub

Private Sub Workbook_WindowActivate(ByVal Wn As Excel.Window)
    'MsgBox "Activated and disabled"
    Application.CellDragAndDrop = False
End Sub

Private Sub Workbook_WindowDeactivate(ByVal Wn As Excel.Window)
    'MsgBox "Deactivated and enabled"
    Application.CellDragAndDrop = True
End Sub

Private Sub Workbook_Before_Close(Cancel As Boolean)
    'MsgBox "Closed and enabled"
    Application.CellDragAndDrop = True
End Sub
