Capturing packets from ethereal now saves the capture in an "anonymous" buffer. That is, it's

a random name chosen by tempnam(), unknown to the user. If the user decides to save that
trace, he then uses File | Save to save it to a file. File | Save As lets him make a copy
of his named trace file as well. I also updated my e-mail address in the various credit
locations.
