flash actionscript: There is no TWEENS or EASING component in my Flash MX2004Pro components
directory. Is there supposed to be one? The tutorial script I copied to study
and examine does not work, and it would appear that an mx control is needed in
my library. Is that correct? If so, where do I get them? Thank you.

Look in:

Macromedia\Flash MX 2004\[language\First Run\Classes\mx\effects\Tween.as

and to use it in Flash, I believe you use the following actionscript:
import mx.effects.*

And then you can use new Tween(...), search for how to use it on this site...
