I might have done something wrong with my configuration, but I experiment a strange behavior: I always work in List View, and I realized that when I enter the Dropbox folder, the view switches to Details View. I can turn it back to List View, but if I close the lister and reopen it, it is back to Details view. This behavior happens only in the Users/user/Dropbox folder and its subfolders: anywhere else, I am in List View. Any idea on what might be the source of the issue?
Hover over the format lock in the status bar and a message will appear telling you which format(s) are involved. Edit them under Preferences / Folders / Formats.
It was on "OneDrive". I disabled it, discovering all these view customization options. Thank you!
