dotonemanband, do you have a track in the track view ?
For me the Now Time cursor in the track view moves back and forth with the slider by a minimum of one measure. If I'm zoomed out quite a bit, it'll move maybe 10 measures at a time. It always stays visible in the track view which will scroll to keep it visible.
However, I don't see the Now Time cursor in the Piano Roll View, though I think I should. There have been several problems reported regarding this view. If I click once in the PRV I see a (very thin) line, but it disappears as soon as I do anything. It's visible while a track is playing then disappears again when it's stopped. It remains invisible if I use the slider to move it back and forth.
Could you give us a bit more detail as to where you are, like in which view ?
