Can't unlock tracks, or copy and paste?
Once I lock a track, and then save the project, I can no longer unlock the track and it is set in stone forever. I click on the track lock button and nothing happens—it stays locked, no matter what I do. The problem persists even when I quit and reopen Garageband, switch to a different project and then back, or even clear my cache and restart my computer. The only time I am able to unlock a track is if I have just locked the track for the first time and haven't saved the project yet. This has been extremely frustrating and has led to the complete failure of many of my current projects. Additionally, I can't copy and paste track regions like I used to be able to in older versions of Garageband. The region is "Copied" successfully, and Paste is not grayed out, but when I click paste, the timeline simply moves one "div" to the right and nothing is pasted, no matter what track it's from, or what length the region is. Why can't I unlock tracks, or copy and paste regions?
