This should not be. Does switching of other keywords has any effect
on the highlighting in your buffer? Are you sure you are loading the
correct ESS and not some old version of it?

So let's try to figure out what is going on. Please paste here the
values of the following variables from your ESS buffer (C-h v):

  font-lock-keywords
  font-lock-defaults
  ess-font-lock-keywords
  ess-font-lock-defaults

Yes, you are the first to have a font-lock problems in 12.09.
