I finally got around to updating my Adobe AIR apps to the latest version of the runtime. Argh.
They keep changing the sandbox! It is incredibly annoying to have to work around the sandbox, and then to have to go make seemingly arbitrary tweaks on every version update.
Mostly, I did it so that I could get a free Thawte AIR developer cert from the Adobe Air Marketplace. Those things cost $300, and Adobe is giving away 125 of them to AIR developers who post apps there.
