The piano radio button does have an underline.
I was told awhile back, all piano real tracks have real charts.

I do have "Note Names" selected in Notation preferences.

This worked for me in ver 2009.

Trying to verify it's not my machine/setup that's doing this.

I can see note names for melody/soloist tracks.

I can see notation for piano real tracks .... but note names do not show for piano real tracks.
