How to display note names in key editor

Dear friends,

I’ve got the problem with displaying notes name. At first they were displayed, but in one moment they’ve disappeared and nothing brings them to light (neither zoom in, nor zoom out)… Please help to display them again! I changed nothing in preferences of my Cubase Artist 7.05.

You have to zoom in vertically, and/or deactivate the “Note Expression Data” button on the toolbar.

Ahaha, thank you very-very much, the answer was on the surface)
