In WL 8 and earlier, vertical zoom with the zoom wheel also showed a vertical scroll bar.
So if I zoomed way in I could then raise or lower the zoom bar to center the zoom, say from 0-100hz. This is particularly useful when in spectrum view at high resolutions.
In WL 9, I can use the zoom wheel to zoom in but cannot adjust the vertical scroll bar to zoom into 0-100hz. No vertical scroll bar shows up. Is there a better way to accomplish this?
