Yes

The data being observed is a TN3270 session (basicaly Telnet for a mainframe in
case you are not familiar with it). It not that the data is wider than the
window per se. It is that there are [probably] no CR/LF because TN3270 is a
full screen client. If I'm an looking at the stream in this regard then, I
would not expect it to wrap in the window based on that. However to analyze
more effectively what is going on, "forcing" the data to wrap in the window as
in the .0a version, would be most useful.

I don't think it a matter of there being a real problem. Its a matter of
practicality- if the data wraps the net effect that you get more data on screen
in the window (you only need to vertically scroll. Now I understand that
choosing *where* to wrap the data in this scenario would also be a question but
as the "Follow TCP Stream" window is a adjustable to a degree, I would perhaps
that window width should determine line length. That way you as programmer
don't have to decide between 72, 80, or 132 characters wide. Thus again leaving
this up to the user to decide how they want to see the data stream.
