Universal listing format for all folders

Running Opus11. Whenever I open a folder of any kind in my default lister, I want the contents to be shown in "List" format rather than "Details" format. How can I accomplish that? I use a dual display (side-by-side) in my default lister, and I have set the format for the folders that are automatically displayed to "List" and then saved as the new default lister (using the Settings menu), but when I close the lister and then reopen it, it has defaulted to "Details" in both screens.
