  You did the right thing. It was one of my (many?) faults.
  I overlooked the effect of one of the last changes done before
  preparing the release.

  help.start() uses standard Windows association between file type and
  application,i.e., if html files are not associate to a browser 
  it fails. This is the reason of the warning. I have not looked
  to the source but I suppose that we can modify actual behaviour
  to give the warning only when actual implementation fails.

  The distribution misses a file used by the search engine. 
  However, at least on my system, it can be generated on the fly executing

  from a running R process (or from Rgui or from Rterm)
  Indeed, to reproduce the behaviour you reported, I had to
  do a fresh installation. On my "real' installation, since I
  added some packages and runned "link.html.help()", all went well.

  Since we are on the topic (search and version of IE), I noted
  that using IE4 on a Win98 machine, when I click on 'aplot' or
  friends I get two html pages, the first with the rigth informations,
  the second blank. So, I have to click on the "previous page"
  button to look to the results. On the same machine and on the same 
  R installation, if I use Netscape 4.04 as the default browser
  all works as expected (i.e, no 'second' page). So, my
  conclusion in this moment is that the problem is due to the
  IE4 Java VM not to R. I haven't test IE5 but I would be glad to
  know what happens.
