Two months ago I cut a music video in VSE with many movie strips laying synchronized upon each other (on different channels). I loved how the preview window always showed the current frame of the strip handle I was just dragging. This even worked when there were other movie strips located "above" the strip I was editing (I think the preview channel was set to "0").
Now I'm on vacation and want to cut another music video on my laptop (Blender 2.8), but somehow the preview window is just showing the frame of the channel which is set in the N-panel. Just a still frame of where the playback cursor (line) is located.
Am I missing an option which I do have to check?
Thanks for your help in advance!
