first I want to apologize for my bad english, I chose this forum too because the german forum seems to be very inactive.
My problem is that I edit projects with several tracks on audacity v.2. If i want to mark a place in a track, I automatically mark it in all the other tracks. If I want to delete or cut it out it does not happen in the track I want to edit; It happens in all the tracks I have. So I have to copy every track I want to edit into a new audacity window/project and after editing copy it back to the main project.
How could I do this better?
