I am working on an AIR application at work and I thought I would post a little gotcha when creating an application that does not use the default system chrome.

The documentation says to set the systemChrome to none, and set transparent to true and that will turn off the chrome... well... almost. If you are building a Flex based AIR application, you also have to set showFlexChrome to false as well, or you still get the flex chrome... Hope this helps someone :)
