@Martijn Pieters Zeigen Sie mir doppelte Frage, warum es doppelt markiert. –
Sie haben dieselbe Antwort auf mehrere Fragen gepostet. Du dachtest, deine Antwort auf deine eigene Frage habe auch auf die andere geantwortet, also hast du deutlich die Antwort gefühlt, die auf beide angewandt wurde. Ich sehe jetzt, dass deine Antwort zu dünn ist, um diese Schlussfolgerung zu stützen, ich habe diese wieder geöffnet. –
In Zukunft wäre es hilfreich, wenn Sie Ihre Antwort detaillierter machen könnten; wie in welcher Version etwas veraltet ist. –
