Unable to sync error message prevents autosyncing

Endnote X7 (os x 10.11) has a habit of preventing itself from syncing by leaving the error message that it couldn’t sync in the foreground; this disables auto-syncing. I wonder if there’s a way to display the message such that when a good connection is reestablished syncing could go on (and even, possibly, removing the error message once mission is accomplished). It happens way more than is useful. tx
