Page scrolling in track view

For some reason my track view is no longer scrolling to the right to follow the now time.  The now time line sweeps smoothly across the page, disappears but the page does not change.  The entire song will play without the track view changing.  HELP please! 

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.

I usually blame my cat or granddaughter when that happens to me
