  We had the same problem with NN on our machine; in fact its the only
complaint I had about the entire package!  NN is a wonderful newsreader.

  Anyway, the one-line-fix below corrected the problem entirely for us.
Apparantely there was a problem with the CTRL-H key being trapped by the
key binding routines before it was identified as a back-space.

  Here is the fix.  The below one-line-fix is in "term.c", in the function
called "get_c()".  Simply add the one extra line.  It worked for us; we
are running UNIX 5.2 on Plexus hardware...  Hope it helps.
