what's an event list ?

No offense intended but I also use the event list view alot. It is pretty essential to my workflow.

Having loaded up the early release yesterday I too am loving note chase. I use event list a lot too for editing patch changes on external gear like mixers and guitar processors amongst other things. I do a bit of copying and pasting in it, but clearly not enough to have discovered the bug. Ignorance is bliss I guess:)

I think the event list is a specialized feature that's used by a small minority of users. Personally I've never found a use for it, and most of my projects are very MIDI heavy. However I can imagine that if you're working with large, complicated orchestral scores driving orchestral VSTi's with very intricate MIDI programming then it would be essential. For my purposes, I see it as a "debugging" tool which is nice to have handy if I need it, which I never have. 

Since this thread has already been derailed and is no longer on-topic, the copy/paste bug referenced by Jerry is not specific to Event List or Staff View.  It will affect anyone who uses Paste Special and the Destination Track field.  For example, you can no longer copy clips from Track 1 to Track 99 using Paste Special without having to navigate to Track 99 and put the track into focus.  This is a regression bug that occurred in SONAR 2016.08 and was first reported in the Problem Reports forum here: http://forum.cakewalk.com/FindPost/3506138.
 
I can only speculate that the work on Ripple Editing involves a lot of changes and possibly a complete re-write of the Copy/Cut/Paste logic and that the bug lives in the code that is being re-worked.
 
Sorry for adding to the OT status of this thread, but I wanted to provide clarification of the issue.
 
Now, back to your regular program. 
 
Hope this helps,
