Ticket #48811 - Console window could be hidden after login via consoles on multiple hosts
    
    Bug Description: When Console is displayed, it uses the values from the
    preference to determine the location and the size.  The preference is
    stored under o=netscaperoot in the config ldap server in the centralized
    manner.  But the values depend upon the window system resolution.  That
    means the location which is good on a window system may not be valid on
    others.
    
    Fix Description: Compare the location from the preference with the display
    size.  If the stored location is outside of the display, reset it to the
    centre.
