Vegas has long had this behavior which I consider to be a silly quirk that I should just deal with, a limitation of the program, but perhaps someone can explain to me why it occurs.
For instance, today I was pasting things in from another Vegas project to a blank timeline. I decided to delete something from the new Vegas timeline and upon deleting it discovered it was duplicated directly underneath. So I delete that. Then there was another one underneath.
How do I make Vegas cease this annoying "feature". Pasting to a blank timeline shouldn't cause 15 of the same clip to sit directly on each other, should it? I should note, this seems to happen randomly in 7 and 8 all the time.
