Clicking menu "Setup/Sound" toggles a check mark. When checked, notes sound when placed, clicked, or moved.
Beams (sometimes called ligatures) are briefly explained in the "More Information/Music Notation" section of the help file, but there should be an example. You can see examples at http://piano.about.com/od/musicaltermsa ... e-beam.htm I found this and many other references by searching for "music note beam".
