Cannot edit one track without editing all tracks.

I opened a very old project in new Sonar. At first, pro channel wasn't available but it has gradually become available on some tracks. When I try to copy and paste one selection of one track As I paste it every other track moves the same number of bars as the pasted clip. Confusing! Any ideas?

Sounds like you have Ripple Edit accidentally enabled.
