I think this is the answer I’m looking for.

Basically I have a “alert” box that pops up when an error accurs. Now my file is composed of this, basically I have a index.swf that is the shell, it loads in sub pages into a movie clip located say x:100 & y:100 (shouldn’t matter). The dialog box command to place it’s self center in the screen is:

```auto
 
this._x = Math.round((Stage.width-this.width)/2);
this._y = Math.round((Stage.height-this.height)/2);

```

This works fine if the alert box is in the index file, but when it’s in a sub page the location is screwy since it’s the movie is at x:100 y:100. I’m trying to find a way to make it center itself no matter what by converting the x&y coords.
