Only guessing as I know little about the Mac system.. But if this were to happen on Windows I would suspect a setting in Windows that starts a screen saver in xx minutes while the system thinks MA is running as a program.
In Windows we can run the MA in either mode, as a screen saver or.. a program. Perhaps... this is happening to you as well.
Ludwig Wittgenstein (1889 – 1951)
The limits of my language are the limits of my mind. All I know is what I have words for.
