I have an executive who using Yahoo a lot. He's complained about not being able to watch Yahoo videos through Google Chrome.
Already reinstalled Google Chrome and Adobe Flash V12.
In investigation I verified Adobe Flash Player is up to date (v12). After a lot of google reading I've found the only way to get it to work is:
Go to chrome://plugins and disable Adobe Flash plugins. Once this happens I am able to watch videos from Yahoo. I don't like this fix b/c you can't watch videos from YouTube and CNN which use Flash.
I can watch in them in IE10 and Firefox.
