[Ethereal-users] TCP Stream Analysis tools not working

[Chad Hall <chad_hall@xxxxxxxxxxxxx>]

I have a capture of TCP/IP traffic taken by Sniffer Pro which I have 
loaded into Ethereal 0.9.5 running on NT 4.0.  I am trying to invoke the 
analysis/graphing functions, but no matter what I do I get a warning 
dialog with the message "Selected packet is not a TCP segment". 
Everywhere else, Ethereal seems to think it is a valid TCP segment.

Any thoughts on what I may be doing wrong?  Have I perhaps missed 
something in the installation?

Thanks,
chad
