In the Export Audio… dialog, the scrolling lists for “Select Flows to Export” and “Select Players to Export” are only tall enough to show two tick boxes. If you have a lot of flows or a lot of players, the scroll bar thumb becomes too small to use. With only two tick boxes visible, it’s a little hard to scroll to and tick the exact flow(s) or set of players you wish to export.
Depending on your screen resolution, you should be able to resize the dialog to your preferred size. Dorico will then remember the size and position of the dialog when you recall it later on.
Thanks, Daniel. Very clever! Vertically resizing the dialog expands those lists. I should have thought to try that before posting.
