autoLoad on mx.screens.Form?


I have started to create a Flash application that has quite a few screens and they all have quite a few components on them. Because of this, when i run the swf it takes ages to initialise everything before im able to use anything.

I have seen how its possible to set the autoLoad to false to speed it up so they only get loaded when they are needed.
Basically i cant work out how to get this working, such as where to put the code to load them once i have set autoLoad to false etc.

Can someone please provide so basic code about how to not load components on a screen until the screen is loaded.
