Please create an MXD setting option that automatically initiates the “Refresh Button” every 10, 20, or 30 minutes (user can choose).
All of our MXD's consume much of the data from an SDE outside of our secure Local Area Network. Our security staff allows limited time for the connection "pathway" to stay open. If the MXD is open with no action for a half hour, then the "pathway" to the outside SDE is closed and the user needs to re-open the MXD.
We tell the users to click the Refresh button if they are not planning to use the MXD for over a half hour, but they usually forget as they are deep into other applications. When they come back to ArcMap all the connections are lost, there work is gone, and they have to reopen the MXD.
