I'm 10 minutes away of finish a 2 cameras Jazz band project when X8 decides to disable scissors for me on the overlay track. Needles to say that I used the scissors countless times on this track.
** No project scissors when the scrubber over this clip also...
***No multitrim for that clip.

It's
crazy but I think found the culprit, I have basic motion on the clip. It is to slide to the right at it's end, I removed that motion and gain the scissors back.
Please check on your X8.
