Hello, all. Rather than resetting the colors and rebooting all the time, I would advise simply setting up multiple profiles on your machine. Then all you have to do is log out and immediately log back in under a different username and password. This may take a bit of time to set up, but given how long a machine usually takes to reboot, I'd say it's well worth the effort. Under the Sibelius profile, you could also have an older version of Sonar running that used the old color scheme so that you could run both apps at the same time. Satauna
