When i write window based systems i always use a Screen Manager.
when i can control and manage and display object on my screen.
Every display object need to extends ScreenContent class, then
he can attached to the screen manager.

As you can see, you can add more functionality this is example only.

FMS blocked port detection – ActionScript 3
FMS block port detection – ActionScript 3
The fms port (1935) closed on many office firewalls, the problem
is that flash had 30 sec timeout before tunnle it to port 80.
Becouse that i write little script that use socket object to test the
port and tunnle it to http when port 1935 is closed.
