Several IP addresses fail to display a Timeline graph. It happens when pinging the name or pinging the IP address. If it fails with the name, it always fails using the corresponding IP address. Some IP addresses fail that do not have a corresponding DNS name (but not all). When it fails, the DNSname in the last line of the trace graph is shown as "---------------" even when a name was used in the "address to trace to" field. This happening on version 2.03 - I have not tried any of the 2.20 beta versions.<br><br>-- <br>Bob Holloway, Unisys Corp., 2476 Swedesford Rd., Malvern, PA 19355-9700
