Even a blind squirrel finds a nut.
I couldn't get the new wgn radio stream to play, so I wrote them a note. 
They replied with in the next business day, imagine that mlb!  I still 
couldn't get it to play using IE 7, no matter what I did with the pop-up 
blocker and cookey settings.  So I tried the same experiment with firefox, 
and what do you know, here was wgn radio.  Since they asked me in their note 
if I had flash player 9 installed, and I do, I went to gameday audio and 
tried the same thing.  I think I would have the game if I had payed for the 
service, at least that is what the dialog that I never saw with IE7 
indicated.  So if you can't get it to work, try firefox, if you can get it 
working with ie7, information about your settings would be appreciated.
Maybe somebody else wants to try my experiment.  Needles to say, I set 
firefox as my default browzer, which I have been thinking of doing for a 
long time.
