In AS 3.0 we just create a new object from a class to attach a MovieClip from the library to the current stage. Does this always occur immediately, or is there a chance of some noticeable load time before it appears? I ask because if the clip in fact loads, I would like to know how to access its loading progress so I can display a preloader. Can anyone help me with this issue? Thanks.
