If you have the "Email Sound Alert" turned on, you will hear an "Oink Oink" whenever you receive new mail. Recent updates to the Chrome and Opera browsers broke this feature. What we found is that these browsers have stopped building in support for Flash. This seems to be the way that the industry is headed, so we needed to find an alternative.
We've just made a change to the site that should have this fixed. The oink sound is now played using HTML5, with the ability to play sound using flash on older browsers that don't support HTML5 yet.
Please let us know if you run across any odd behavior with the "Oink" alerts.
