The Oxygen XML Editor application can display a notification when disconnected from the repository.
This feature must be enabled by an administrator by running the setEditorOnlineModeCheck.py script. See Administrator Scripts.
When enabled, Oxygen XML Editor periodically verifies network access to the server. If access is lost, a dialog appears in the bottom right corner of the application notifying the user of the disconnect. The user can continue working in the editor, but cannot check in the document until network access becomes available again. The dialog can be closed manually, or it will automatically disappear in 10 seconds.
