I had read and followed the documentation, had the cue mix Z latency option functioning properly, then that status changed after I "upgraded" to the latest version of UC, so I went back a version and got a couple good options back. like being able to minimize the mixer control screen once again, but didn't get the Z option & don't seem to have a way to. So I need advanced-level options cuz this problem isn't referenced in any of the info I've researched.
