When I try to look at my video in the library, it's now impossible. I can see the image in the upper window, but there is no response when I clic on play. The time is also at 0:00. When I export the videos on my desktop, I can look at them with Quick Time.
Maybe the other problem is connected to the first one. In Development, it's impossible for me to clic anywhere, there is no response. Impossible to work on the photo.
