System cutting off notation symbols
This is a problem with your display driver.
The best general solution is to get an update from the manufacturer that corrects the limitation in the driver. However, you may want to try another option. You can add the OutlineThreshold option to your WIN.INI file under the [TrueType] section, as shown below:
; The OutlineThreshold option can sometimes be used to get the
; NoteWorthy Composer music font to be fully displayed by a
; buggy graphics display driver
This very often will work, but it also causes some display distortion on many types of equipment.
