When users are automatically logged out after a period of inactivity, the window should revert back to the log in screen so that you know you have been logged out.
I recently spent half an hour making changes to a template that I had open in a window before going to lunch. When I attempted to save my changes, the system then took me to the log in screen - I lost all my work.
ALTERNATE SUGGESTION: give etap admins the ability to specify the period of inactivity/auto log out for our users.
