I am evaluating DOpus - so I am very unfamiliar with this tool.
I set up a the Lister in the 'Single' style with the columns and formats I wanted.
Then, from the menu, I selected 'Settings >> Set as Default Lister' and responded appropriately to the warnings asking me if I really wanted to do this and to have the 'Settings >> Preferences >> Listers >> Options >> Update Default Lister automatically when closing a Lister' setting disabled.
But, when I select the 'Dual Vertical' style the new Lister that is displayed on the right side of the screen doesn't have the same columns that I want.
What am I doing wrong?
