appear on the map where they
have selected.
Just use onMouseDown and onMouseUp handlers for the movieclip that
contains your map. Record the _xmouse and _ymouse at each event. Those
are the diametric corners of your new selection.
Oh, and if you want a box to appear and resize in sync with the user's
movements, have the onMouseDown handler create an onMouseMove listener,
and resize the box each time that event fires. Then onMouseUp doesn't
need to draw the box; it can just remove the onMouseMove listener and
leave the box at its last drawn position.
