If one moves a clip to the right, the mode will act accordingly by inserting into the sequence in the place where it was dropped. It you move it to the left, and release, it will drop in a random place, even splitting clips. Basically, it can be used in one direction, but not the opposite. We’ve been on many sites, and no one seems to have a solution. My editor just posted a video in the Avid Users group on FB. Marianne, from Avid, is usually very informative, but she is dealing with a family emergency. Any help you could provide would be greatly appreciated! Let me know if you need more details. We’ve tried everything we can think of. Thank you!
