That’s this one, yes? How to lock track focus?
That is currently logged on the Audacity bug tracker, as a top priority bug. The cause has been identified, and I’m very hopeful that it will be fixed in Audacity 2.3.1, which is scheduled for release next month. The release will be announced here on the forum, on the Audacity website, and on our social media (see links at top of page).
OK, so that is “solved” for you?
I’m not aware of this issue, so if/when you have more information, please start a new topic about it so that we can look into it.
