Just for the record, if someone is investigating the issue about changing history frames simultaneously with cursors:
I somehow managed, to change history frames simultaneously with the intensity. After the menu closed automatically, i could not reproduce this, when opening it again.
Edit:
I can now reproduce this. It only happens after the sequence has been finished or you hit stop, and the navigate history is used. But only if the frames number "button" is NOT activated. So a simple solution would be, to just activate that by default (if the user experience would not suffer).
Edit 2:
Yes i know, the quality is bad. But just look at the waveform, there you can see, that frames are changes and the intensity gets low.
