I have been working on a project for a few days now mailnly cutting out unwanted portions. I had a gap & tried to drag an event to the left. What I found was that I had several copies of the same clip stacked one on top of the other. I don't use the takes feature. As I selected each clip & deleted it I found another copy of the same event below it. There were 4 copies one on top of the other. I would like to know what I could have done wrong so that i don't do it again. Any Ideas?
