I have a small problem with Vegas 15 that I really can not solve, I usually get angry and end positively without having to disturb forum users, but this time I am forced. The preview screen is no longer, as you can see from the photo with a green arrow, in its place and it can be moved. First, photo red arrow, was firmly anchored and immovable. Maybe I did some wrong maneuvers. Later I put Vegas 15 all in default but the problem was not solved. I think it's a trifle but that I currently do not know how to solve. I ask the lights to people much more experienced than me! Thanks in advance!
