Thanks for the link...only read the first page, but leaning to believe something is amiss with Apple.
I'll have to get back to it, to see how the 'saga' ends.
Unlike the OP, I have no issues with I-tunes, only installed so I could download a pod-cast I was interested in. So I'm not doing as much as the OP in the utilization of the app. Perhaps, if I was, I too would be experiencing problems. I also listen to internet radio on occasion, I don't know if any of those 2 functions require the 'Bonjour' service. Persistent errors in the Event Viewer are my only bane.
