The Scoreboard Alert functionality (click on little [+] sign to subscribe for each game) will display alert-box style messaging at the bottom right corner of your screen to announce various game information when available. This is now working properly.
However I have never seen it work properly. Might be that my screen is small and I need bigger real estate to see the bottom right corner. Or it might be it doesn work.
They have done a bunch making gameday better, so I'm not complaining. But I don't use the alert feature.
There are a few things with the New York Yankees that never change. That's pride, tradition, and most of all, we have the greatest fans in the world. -Derek Jeter, 9/21/08 -- last words from old Yankee Stadium
