Hi Walter,
Thanks for your tip. I will give it a try one more time. Do you think when you have so many layers, more than 900 of them, you might experience this issue? Is there any limitation on number of layers you can keep visible on timeline?
Again, the playback was showing these layers i composition and selecting a hidden (seemingly) layer and using in and out point shortcut keys were also working fine, the only thing I found irritating was not being able to see it’s normal behavior.
Thanks again for your time.
