Hi Larry,
That's the [Track view] Options > Click Behavior > Left Click Lock Scroll feature. You can either disable it or leave it on. When on, if you click on an object/note during playback, scrolling will stop so you can perform edits. When you want scrolling to start again, just click anywhere in the background of the clips pane or PRV.
