Hi. Thanks for replying!

Yes I am running from the BB hard drive it shipped in.
Yes I do get the the audio c chord to play the ZZjazz.sty: jazz swing style default.

So first, following the tutorial, I choose a style from the style picker. Then, use the keyboard method for adding chords starting with the first measure. At first all I got was a ping sound regardless of the letter I was trying to type. Today I actually get different pitches from each different key.

I also see that in addition to the first measure being highlighed in black, other measures seem to randomly be highlighted at the same time.

Any thoughts?
