The CTI won't do this on its own. What are you doing when this happens?
If you are playing your timeline and you move the CTI, it will continue playing until you stop the playback.
If you have rendered your timeline, playback will automatically begin after the render unless you change the preferences.
Thanks. I got it now.
It's always helpful when you report what you discovered, robusto. It might help someone else in the future!
Just meant that I followed what you indicated and now have the timeline control I need. Thanks again.
