Yes, that's exactly what is happening.

I see this when I'm using mmm-mode (Multiple Major Mode Mode) with 
html-helper and cperl as the two major modes in effect. I use mmm-mode 
to edit HTML files which have Perl embedded in them; giving the Perl 
code a yellow background makes it easy to find. But with hl-line 
enabled, the current line has white text on a yellow background.

I do remember seeing this happen once before, but if I remember 
correctly, whatever caused it wasn't useful enough to spend time trying 
to fix it, so I quit using it. I can't remember what it was at the 
moment.

I'm using a version I built from CVS for Mac OS X Carbon a couple of 
months ago (emacs-version says it's 21.3.50.1). I don't have a 
list-text-properties-at command, but I do have 
describe-text-properties. Here is its output when point is in some Perl 
code in mmm-mode:

        Text content at position 13268:


        There are 2 overlays here:
         From 13267 to 13316
          mmm                  t
          beg-sticky           t
          end-sticky           t
          evaporate            t
          mmm-evap             t
          priority             1
          name                 nil
          display-name         nil
          mmm-mode             cperl-mode
          face                 mmm-declaration-submode-face
          mmm-local-variables  ((font-lock-cache-state nil)
         (font-lock-cache-position #<marker in no buffer>))

         From 13268 to 13281
          window               nil
          face                 highlight


        There are text properties here:
          fontified            t

As described above, what I am seeing here is a block of Perl code with 
a yellow background, where the text on the current line is white. What 
I would *like* to see is exactly this, except with a blue background on 
the current line.

Thanks again,
Matt
