Don't know exactly what to tell you to do.
I know if Google Chrome wasn't going to work for me, then I felt to do a fresh re-install of windows xp.
Fortunately G-Chrome works good for talkshoe live calls. I can still use explorer to listen to the recordings.
Firefox still works for other types of audio streaming.
However, I do notice now and again that if I have both browsers opened (firefox + Chrome) and I am playing an mp3, it sometimes freezes up. When this happens all I can do is to re-boot the system.
