Is there some reason that the jog control button (on the same row of the Source/Record Viewers as the playback buttons, and to the immediate right of the speaker button) does not show up on my Viewers?
This is the button that looks like a left-arrow/dot/right-arrow. I know it's supposed to be there because it is shown in the Ripple Training videos.
Got the answer. It was a Mac display resolution issue. When I changed from "Default for display" to "Scaled" and chose the icon just to the right ("More Space") of the Default, the jog control buttons appeared.
When using "Default for Display" with a large external monitor connected, the jog control button is visible on the large monitor, and not on the MBPro.
Thanks to David Weiss for talking me through this. No substitute, sometimes, for two people on the phone trying the same thing on different Macs.
