Auto-Refresh add-in that doesn't refresh active page
A number of our employees switch between multiple web based apps. Most of these apps need to be refreshed periodically to keep from expiring. They have installed some auto-refresh add-ins, but unless they are manually disabled for the current tab, they will auto-refresh even if the user is actively entering form data. When this happens, any work they've entered is erased.
Can you tell me if there is an auto-refresh add-in available that is able to monitor specific tabs for active work, and NOT update them?
