                      _('Do you really want to close this dialog, discarding any changes?'))

                    return
        QDialog.keyPressEvent(self, ev)

Chaley, thank you kindly. I was prepared to AstroGrep through \calibre-master\src\calibre\ to find the keypress event filter that keeps Calibre itself from closing. Your snippet is much appreciated.
