I must be missing something, since I upgraded from 3.4.6 to 3.6.8 I no longer see the SEQ/ACK analysis section under TCP. I checked by loading the same capture in both versions. I have also unchecked - Do not call subdissectors for error packets - in both versions. In 3.4.6 I can use the filter TCP.Analysis.duplicate_ack and I find 34127 dup acks. I have looked at the actual dup packets to validate these are real dups and they are. When I load the same capture in 3.6.8 the same filter finds 0 packets and the SEQ/ACK analysis section is missing. Help!
