I don't doubt that the Now time in the PRV agrees with the Now time in the Track View.
The PRV is not in the multi-dock, rather I use it in its own window.
This is very frustrating when I am putting MIDI drums to a free-form audio track which was not recorded with a click, never mind bar lines. >8]
I locate a peak where a note of interest occurs and set the Now time to that point, then move the cursor to click on the PRV which is behind the TV, and apparently some artifact on the screen that I move the mouse over causes the Now time to change.
I'll see if I can make a video of this happening.
