I’m running Audacity 3.6.4. Suddenly the waveform display has a blue horizontal band above and below (with “audio 1.1” at top left that I’ve not noticed before), and occasionally the envelope tool cuts in and out for no reason, often with a vertical line of four small circles crossing the waveform. Can I prevent this happening, or is it an “improvement” which I’ve not asked for?
EDIT: Fixed! F1 switches it off! (I must have switched the Tools Toolbar Envelope option on by mistake - F2).
