Thanks, learned something new! WaveLab indicates unsaved changes in the montage by the red corner on the tab. Locking a track doesn’t trigger that marking.

There are two types of changes: those that are undoable, and the rest. Only the former cause the red tab. The concept is somehow, everything that affects audio, should be unodable. The rest, like zoom and scroll position, etc., are apart.

Thank you for the explanation!
