ActionScript 3.0 :: Sprite Drag Area Is Too Big?

I've dynamically created sprites with graphics and added a text field dynamically to each sprite, displaying different text. These sprites (checkers in this case) are draggable. Without the text added to it, the drag area is very precise, dragging only when the circle is selected. However, when I dynamically add the text, there's a significant portion underneath and to the side of the sprite that is also draggable. This is really annoying when one sprite is placed above another because trying to move the sprite below causes the sprite with a lower y coordinate to move even though it shouldn't. When I tried to define a width and height for the text field to avoid this unnecessary space, it made the text much too small!

There must be some way to make it so only the graphics and text are draggable. I don't even mind if there is a square (like the old Flash 5 movie clip square) around the combined object, but there shouldn't be the white draggable space.

For reference, here is the code:

Code:

var i:int = 0;
var Rwidth:uint = 20;
var Rlength:uint = 20;
