Multi-monitor Support in AIR
I've seen several people ask about multi-monitor support in AIR. The answer is: it's there, and it's very good.
Take a look at the flash.display.Screen class (AIR only -- not available in the Flash Player). It contains the following properties:
boundscolorDepthmainScreen(for getting a Screen reference to the main screen when there are multiple monitors)screens(an array of Screen objects for all attached monitors)visibleBounds(returns a Rectangle that excludes unusable portions of the screen like the taskbar, menu bar, and the dock)
The Screen class also contains a very cool function called getScreensForRectangle that returns an array of screens that intersect the specified Rectangle.
We've also added a ScreenMouseEvent that is dispatched by SystemTrayIcon and gives you the coordinates of a click relative to the main screen as opposed to an application window.
For a relatively simple example of the Screen APIs in action, check out SPF on the Adobe Labs Sample Application page.

Christian:
There is no sample app called "SPF" or any verbiage relating to multiple monitors on the labs link you provided. Help?

Any reason this isn't part of the Flash Player? Is there any possibility this will be part of Flash Player 10 ?

It's always possible that AIR APIs could find their way into the Flash Player, but I doubt the Screen APIs will be integrated anytime soon. They won't do much good since you can't do thinks like open new windows.

I've looked in to this a while ago and build a ScreenManager to move and activate screens on one of the screens.
Take a look at this;
