If a user tries to disconnect from the z/Server while MVS edit sessions are still open in the client, a confirmation dialog will warn the user that the editor(s) will be closed before disconnecting. If the user selects 'OK' in this dialog and the editor(s) contain unsaved changes, individual dialogs will appear for each editor, asking whether to save the changes or cancel the disconnect action. If a user selects "Cancel" in one of these dialogs, this message is written to the error log.
