I do not see this in linux, but I noted that the first time the output is sent
to the results table or the log table, it takes an unusual amount of time to
show the contents of those windows (they open but stay gray for several
seconds).
I think that this started a few updates ago.

It could be to do with the firewall specifically.  The newer versions of
ImageJ listen on port 57294.  If the firewall is blocking this port it would
introduce a delay.  Try configuring the firewall to allow ImageJ to use that
port.

Now I'm curious.  Why is ImageJ listening to a port at all?  Am I missing
something?

Didn't you see the note about ImageJ Genuine Advantage? :-)

Actually, I believe Wayne added code some time ago to deal with a
Windows problem where new images opened in new ImageJ processes instead
of opening in the existing instance of ImageJ.  When ImageJ starts up
on Windows, it checks to see whether there's already another running
instance listening on this local port, and hands off the startup
arguments if so.  Right, Wayne?

The code in question is in ij.ImageJ.main(), if you're curious.

Jim,

It is listening for communication from other instances of ImageJ on the same
machine (but from different JVMs). This way, if ImageJ is already running,
and you launch another copy of ImageJ, the new copy can pass the parameters
to the original copy, then die, and only have one ImageJ in memory at a
time.

==================================================================
Call for Abstracts:

Horizons in Molecular Biology aims to provide deep insights into
contemporary life science research and to encourage exchange among
people from different biological science branches. We invite
distinguished scientists from fields as diverse as structural biology,
developmental biology, cell biology, neurobiology and stem cell research.

By including such a diverse spectrum of topics we hope to broaden
horizons and to inspire interdisciplinary discussions. Through the
scientific and social events of the meeting we intend to improve the
networking of Ph.D. students and young researchers from different parts
of the world. The meeting will feature five sessions with invited
lectures, two poster sessions, three sessions with student talks and

includes an extensive social program.
