Wow! the worked perfectly and quickly!
I'm impressed.

I have always been a proponent of using Sniffer Pro but that is only
because I know how to get around quickly in there due to previous
training.

It appears that Wireshark is alot more powerful once you know what
you're doing?

The TCP dissector doesn't have a "tcp.analysis.dangling_syn" or
"tcp.analysis.handshake_progress" display filter field, although either
of those would arguably be pretty handy. You should be able to find
unanswered SYNs in a capture file here by selecting
"Statistics->Conversation List->TCP (IPv4 & IPv6)", then sorting by
"Packets A<-B". Unanswered SYNs will have zero packets in that column.
