AS3 problem onReleaseOutside


I’m creating a drag(scroll) it is OK.

Have addEventListener and so on for MOUSE_UP(AS3) = onRelease(AS2) and MOUSE_DOWN(AS3) = onPress(AS2). Here my problems start want to make onReleaseOutside. I read, but there is wrote that for onRelease and onReleaseOutside is the same event => MOUSE_UP, but i can’t catch onReleaseOutside event. Any idea how to do it?
