Try turning on "Auto Lock", top right above the Track List... With Auto Lock turned on only the Track you select is active and all others are greyed out and are not "almost transparent"... You will only be able to select\edit notes on that track... With "Auto Focus" on you can click on a note from another track, "almost transparent", and bring it into "Focus"... With Auto Focus on you can also edit notes from two different tracks at the same time by selecting them at the same time...
