Still a few issues
1) Audio folders make projects/Sonar Platinum still unstable. I have to remove audio tracks from folders to make older projects work. Support requests that I perform an fresh re-install, but reverting back to 2016.12 makes this work. Problem started with 2017.1.
2) I have re-scan plug-ins after every update.
3) Items set to multidock no longer stay in multidock when re-opening projects. Problem started with 2017.1.
Else all good.
