Grid not visible in Key editor

I just work with Cubase6.5 after years working with C4.
Now in the key editor of Cubase 6.5 I dont see the grid lines well.
Do you have any suggestions to solve this and see the lines better?
Thanks a lot!

Preferences->Appearance->Work Area …

Move the key editor slider to the right.
