Troy, thanks for the help. My Singleton works fine now, I'm gonna see how
does Monostate work.
And Petro. I don't see how your sugestion may help me.

That works for me. There's also a technique where you use an internal
class (visible only within the AS source file) as a parameter to the
constructor, thus causing the compiler to complain if anyone calls the
constructor from outside that source file, but I find that throwing the
error is enough.
Another option is to go with a Monostate, which doesn't require any
trickery in ActionScript. In a Monostate, you can create as many instances
of the class as you want but they're all basically just facades onto a
single instance (usually implemented as just having private static members).
In some cases I like the Monostate better because, depending on the
application, its easier to switch to not being an "oop global" if need be.
