I am running Firefox 4 on Windows 7 and am experiencing a problem loading the main news headline image on the BBC news site. All other images are ok. This problem also occured on my old PC running XP. The image loads but is placed over the headline text. The other user account on my PC does not have this problem. I transferred my Firefox profile when I started using my new PC. I have tried a fresh install of Firefox but this did not work. Help.
