Couple hints from a newbie. Save your veg file often, after you successfully create some changes. Undo works great, but being able to close then reopen the veg sometimes helps save me best. I have also learned the hard way to keep careful track of the order I do things. I had several instances where I had locked a audio portion and forgot it. Then when I moved a large selection, that audio stayed where it was and I had to search for where it belonged with the large selection I moved. Takes practice and the hints these users provide always pop up with ideas I did not try or know about. So many options in VV. Happy reading.
