If a user only has a "read" access right to a folder and the documents within it (NO "browse") and a link to a document URL in that folder is sent to them by email, if they click the BACK button after opening the document, will it simply show a blank screen since they have no browse right? Below is what the folder, subfolder, and document shows when I enter a user's name in the group this setting is for.

p.s. is the ability for admins to truly impersonate a user going to come with Version 12?
