I had previously tried ASM but had problems with the dock which would sink about halfway below the bottom edge of the screen or would disappear. Hoping that a later version would not have the problem, I downloaded version 2.2.10. Unfortunately, the problem persists to some degree. While it works when starting up from my internal drive, if I start from a cloned backup on an external drive, the problem returns. I emailed the developer, but it has been over a week and I have not heard from him. I sent a second email.
