A link back to the previous screen is dependent on the breadcrumbs being available. Breadcrumbs are dependent on the View Page Template. Pro users can create and customize templates. For Free users, we have a set of default templates, some of which have breadcrumbs and some do not. Folders that are automatically created by Camtasia and Snagit do not display breadcrumbs. If you would like to display breadcrumbs on the View Page, you can create a new folder and place content in that folder. If you want viewers to be able to see that folder, I would also suggest setting the privacy to Public.
