Thank you very much, that solved the issue !
Unfortunately now I have a very different issue: When I drag a new video clip into a gap in my video, it does not go inside that gap. Instead, it creates a new video track just above the existing one........

I've been using the program for a week without a hitch, and now two in a row with no solution on any tutorials 😲
In any case, thank you for the help!
