I think it's because q.zoomed = false create a memory space where the
boolean value "flase" is stored, and q.zoomed is a pointer witch point to
this memory space.
New Boolean(false) create also a memory space and a pointer, but with
w.zoomed = new Boolean(false) , w.zoomed point to the pointer of the value
and don't point to the value. So you can do !Boolean but not !Pointer(of
boolean)...
w = new Object();
w.zoomed = new Boolean(false);
trace (w.zoomed);
//false
w.zoomed = !(w.zoomed);
trace (w.zoomed);
//false
test = !(w.zoomed);
trace(test);
test is a pointer to a bollean value but w.zoomed is a pointer to a pointer
of a boolean value... I guess...

Subject: Re: [Flashcoders] Boolean question
Correct me if I'm wrong but I believe the Boolean type is still a
primitive
and should not be instantiated with 'new'.
You could perform casting like this:
w = new Object();
w.zoomed = Boolean( false );
But I don't know what benefit it would give, as Flash doesn't support
typing
on the parameters of an Object instance.

Hi list...
Why does an object's parameter not change if it's instanced as a new
Boolean()?
w = new Object();
w.zoomed = new Boolean(false);
trace (w.zoomed);
//false
w.zoomed = !(w.zoomed);
trace (w.zoomed);
//false
q = new Object();
q.zoomed = false;
trace (q.zoomed);
//false
q.zoomed = !(q.zoomed);
trace (q.zoomed);
//true
