Howdy HB,

To change the clef symbol (and have the notation placed correctly as well), just double-click on the clef symbol, and change it to whichever one you want to use. In your example, you'd double-click the bass clef, and then use the dialog to put in a treble clef, and click "Ok". Now the clef will be treble, and the notes placed accordingly.

ttfn,
Sherry
