Backup Path Failure may cause Citect to shut down.  If a RUN and BACKUP path are both set, but BACKUP path fails, and then an attempt is made to display a non existent page (using pagedisplay() ), the system displays the message "Cannot display page" and then SHUTS DOWN. 

CIT has confirmed this to be a problem in Citect for Windows versions 5.20 to 5.21.  This problem has been fixed in version 5.21 Service Pack A.
