Dictation randomly stops working in Tahoe
I have a problem starting dictation in Tahoe. My system is set up to use an external microphone and to start accepting dictation on double clicking the control key. The problem is that it will often work well but then randomly stop working for no obvious reason. I have been through and double checked all the settings, and switched to my Studio Display microphone, but the problem persists. It looks like a bug because it works well one minute, but stops working if, for example I work on another document and then go back to dictation.
