1)
when I change a picture in extras (to a different one from disk) and then click on "next extra"-Button (=white arrow on blue ground) to change next one, a window appears which asks me to save the first change - correct so far.
When I now change the second picture and a third or fourth and click OK at the end, all the changed pictures are messed up, some are vanished some doubled or tripled and the sorting has also changed regardless of whether I saved or not. - definately not correct.

2)
when I save two or more pictures from extras to disk (using next extra button), the programm then moves the first picture to last position.
