Since upgrading to C9.0.1, I have discovered that, on occasion, Cubase 9.0.1 will hang on quitting. Normally, I wouldn’t be bothered by this because I would simply invoke Force Quit to shut the program down completely. But here’s the real issue: once Force Quit is used, the program can no longer be relaunched unless you log out and back in or restart the computer. That’s report-worthy to me.
I have not found a consistent way to duplicate this issue. It has been quite random so far. I have observed this phenomena approximately 5 times since 9.0.1 was released.
