Remove the feature that shifts the playhead to the right side when I put it on the left side during playback.
It is useless for the playhead to move to the right side of the timeline when I click to put it on the very left side and start playback. It also happens if I move the playhead while the timeline is playing.
I'm not exactly sure what you're talking about.
Have you tried "no scroll" or "smooth scroll" in the preferences?
It might also be "at playback end, return to beginning when restarting playback." You might want that box checked OFF.
