copied audio region won't play
When I copy an audio region and paste it into a different, existing audio track, it won't play back. It is gray, and I can't find any indication (other than that) as to why it won't work. The existing regions play just fine. I've tried quitting Logic and re-opening the project to no avail.. Any ideas would be greatly appreciated.
