The Cubase Pro 10.0.10 Timeline cursor disappears when the transport is stopped. There is only a small 1/2 line in timecode bar above the arrange window. When I play the transport, the timeline is shown but when stopped there is no timeline. I tried changing the line thickness to no avail. For now I am back to 9.5 for music.
I upgraded from 9.5 -> 10.0 -> 10.0.10 on Windows 10 Pro X64.
I will try it on my new mac trashcan soon.
