Well, I am still having the same problem. Nothing seems to help. What is going on here!

I have installed an older version of quicktime. Uninstalled Norton and all related products. Turned on mac firewall. Only used safari instead of foxfire, or explorer. Restarted each time. Beat my head against a wall (sic). Talked to applecare. Visited all the above recommended sites (thanks Lord of the Rings: ). Still no luck.

Someone please help me.
