When viewing a list of questions from the homepage, Questions page, or Unanswered page (and possibly others), the questions tagged with my interesting tags are not highlighted in Chrome. I have observed this both on boardgames.se and android.se. Highlighting is still working fine in Firefox and on my Android phone's browser.
Highlighting does work as expected on SO, though, so the problem is not universal.
FWIW, I'm using Chrome 7.0.517.41 for Linux (Ubuntu).
