Done (as a side-effect of my discarded first attempt at a fix to the
crash Doug Nazar found if you pop up "Find Frame", pop up a filter
dialog box to browse for a filter, close the "Find Frame" dialog, and
then select a filter; some other dialog boxes had the same problems,
namely "File:Open" and "Capture:Start", and I fixed those as well, in
addition to some other problems, e.g.  if you quit Ethereal when there
were "Follow TCP Stream" windows open, the temporary files for them
didn't get deleted).
