V1.5 and audio access

I just upgraded to V1.5 and tried to access a streaming audio broadcast on wsbradio.com. They have a "listen live" bar that would not work. I uninstalled V1.5 and the audio works again. What did the new version stop that wasn't on V1.4? I think it has something to do with advertisements that appear on this page. It that's the case, what do I need to do to be able to use the "listen live" feature?

Thanks...

Take a look at this: try to set the IE plugin to ask you about each thing it encounters, there you'll be able to tell it to allow the ads on this page.

That worked, however, when I said to allow this action all the time, that fuction didn't work. I had to "allow" again when I reentered the same site. Quite a nuisance.
