I set up Flip4Mac to listen to it iin Safari on the Mac and I get the audio. The Safari browser displays a window listing what's currently playing. But repeatedly, partway through a song, it starts playing a song that played a few minutes before. I have to go to Safari and click the channel listing again to go to the current tune. I guess something is making it go back to buffered streams, but I can't find any setting to change in Preferences to make it stop that. Has anyone run into this with any streaming audio ? I never had a problem on a PC, so I don't think it is XM's fault.
