It seems dangerous to force users to download documents regarding concerns rather than have a default option to view them in a browser without actually downloading it..
Whilst it is not iSAMS' concern what happens to a document after it has been downloaded to a users local storage, and that School Policy should dictate what a user does about removing traces of such data when finished using it, it does seem somewhat odd that this is the ONLY method of viewing a document available to us.
Could not iSAMS provide such a method of viewing a document without downloading it, perhaps making it the default method of viewing documents but configurable by each school to fit their needs?
