Cubase 6.5 no horizontal lines in key edit (Mavericks)

Hi, I don’t seem to be able to adjust the preferences to show the horizontal lines in the key edit window! I’m running Cubase 6.5 with the latest update on an 2.3ghz i7 Mac Pro Retina (Mavericks). Any idea’s?

Aloha F,

After looking in, C6.5 ‘Preferences’.

(in the middle) ‘Edit Windows’ section,
‘Horizontal Grid Intensity’ IS working here in C6.5.

However in the top ‘Project Window’ section,
it seems the ‘Work Area Brightness’
has to be set fairly ‘brite’ to see any real effect or change.

Good Luck!
