Deleting parts of one track deletes all track sections

[David Pollock]

Either something changed with recent updates, or I have some unknown option turned on. Didn't used to work like this. When I select a section of a midi track, and delete it, the same amount of track is deleted in all tracks.  I simply want to delete this little bit of one track without moving anything over in that track or any others. Must be something simple, but I cannot find it.

You've got the "Ripple Edit" button switched on in the top-right of the Tracks View.

Thanks Jeremy. I knew it had to be something simple, and despite many years of Sonar use, I didn't know that existed.
