Is a component a Movie Clip?

[font=verdana, arial, helvetica][size=2][color=#4f5044]Hi,

I have been using a “Button” component in conjunction with some Movie clips in a simple script that should move all the movie clips to a predetermined _x position, having been filtered by an “instanceof MovieClip” condition

Problem is, for some reason MX2004 is reading the button component as a Movie Clip & moving it along with the others.

Here is the script.

mybuttonlist=new Object();

 
 
mybuttonlist.click=function()
{
for (i in _root){
if(_root* instanceof MovieClip){ 
_root*._x=50; 
}
}
 
 
} 
mybuttonlist// add listener etc.

Can anyone shed any light as to where I’m going wrong?[/color][/size][/font]
