I haven’t found a good reproducible case, I don’t think dropping a project here would help, but scrub only works about half the time. In this case I’m using the Ctrl-space shortcut, nothing sounds and as you can see the vertical play bar doesn’t show. It triggers but doesn’t follow through. Other times I have gotten it to work though.
It works best if you keep the pointer on the staff, in my experience.
Thanks, hm, yeah just not working here no matter where it is.
