SUMMARY
***
When I select a lot of different segments on the timeline and move them to the side − then the program freezes for a while. Sometimes it freezes for a minute or more. Can you fix it? I have a strong computer and this should not happen, especially when I edit a 1-minute video.
***


STEPS TO REPRODUCE
1. I select several segments on the timeline.
2. I move them to the side
3. 

OBSERVED RESULT
Freezes for a while

EXPECTED RESULT
It didn't hang
