How to change tracks

[Empirical_Audio]

I am dragging tracks from the left field into the right hand field. Then I double-click on a track to play that track.

When I manually try to change tracks in the right-hand field by double-clicking on a different track, it continues to play the previously played track, even if that track has been stopped. Then I can usually double-click on it a second time and it finally plays the right track.

How should I be operating this?

Thanks,
Steve N.
