Hmmm, you too, eh.

If you select a TCP packet you can get some neat graphs which seem to show 
how sequence numbers progress on the stream.

It seems that the person who asked was really looking for the packet that 
caused the remote end to close the window (or what she thought was the 
packet).

I suggested a filter expression that should locate the acks where the 
window was closed, and that she ask the questions on the Ethereal-users 
mailing list.

The pictures have not been updated for a while, either.
