I was disappointed to find that I could not use the \_width  
property of a tweened movieclip instance to know how large  
the mc is at a given time.

Am I just not getting something??

A breakpoint in the onEnterFrame() function shows that  
\_width is always the LARGEST width the movieclip  
ever has – not its CURRENT width. In my case the mc is being  
made larger and larger, using a tween made in the authoring  
environment. The clip starts out tiny and ends up 400 pixels wide,  
but the \_width property is 400 the entire time!

What gives??

i really appreciate enlightenment!
