Hi,

when I attach a MovieClip from the library, onto a dynamically created MovieClip, the library’s MovieClip slightly changes size. Does anyone know why this happens?

Example:

This is the code that attaches the MovieClip and then traces width and height:

```auto

var preview_mc:MovieClip = build_mc.attachMovie(xmlModule.attributes.ai,(build_array.length + 1) + "_module",build_mc.getNextHighestDepth());

trace("-----------------NEW-MODULE---------------------");
trace("width: " + preview_mc._width);
trace("height: " + preview_mc._height);

```

Kind regards,
