I noticed that using the “Ripple All Tracks” and removing a piece of film from one of the tracks (eg 10 second photo in .jpg format with two filters (Mask, Size and Position)) the program hangs (No answer) and turns off. This happens almost every time. In the case when we first remove the filters from this photo, it manages to remove the fragment but it also can hang up, more rarely but in spite of everything, it happens quite often. After turning off “Ripple All Tracks” you can easily remove even the filters on this fragment.
