Mam aplikację GDK, która działała poprawnie w XE12, ale teraz ulega awarii w XE16 po przejściu na GDK: 19. W szczególności wywołanie openOptionsMenu() w działaniu (w tym przypadku, aby otworzyć menu opcji na karcie aktywnej) powoduje, że BadTokenExceptions.Wywołanie metody openOptionsMenu() w XE16 powoduje, że WindowManager.BadTokenException

dotykając żywo przyczyn kartonowe natychmiastowa awaria, a wyjście Logcat powyżej jest zrzucane. Dziwne jest to, że skomentowane openOptionsMenu() jest odkomentowane, a istniejące openOptionsMenu() jest zakomentowane, pierwsze kliknięcie otworzy menu. Druga próba otwarcia menu zakończy się niepowodzeniem, z podobnym wyjściem Logcat (wyjątek BadTokenException jest głównym wyjątkiem zamiast wewnętrznego wyjątku w RuntimeException).
