Actionscript 3 :: Flash/AIR Application Going Fullscreen On Launch (on MAC)?

I've created an AIR application in Flash CS4 with AS3, and the application needs to start up as fullscreen. I put a slight delay on the fullscreen call to get around the fact that flash won't let you start an application in fullscreen. This works fine on windows. However, on Mac, my application has an issue...

It uses this code to go fullscreen on startup: var fullscreen_delay:Timer=new Timer(10,1);// delay to bypass flash's non-fullscreen-on-startup feature

[Code]...

Putting a ridiculously long delay on the fullscreen call (5000 milliseconds) seems to do the trick. I realized this when I launched the application and immediately started mashing the space bar (my fullscreen toggle key), which kept presenting me with the same issue until after 3 or 4 seconds, at which point the fullscreen began working properly.
