AS2 inventory script

I'm trying to modify the below script so that it will automatically drop the first instance of "_item" and snap it to the nearest "slot"

The code works great except I cannot find a way to make it drop the item without the user clicking on it first. This is not my script. You can see it in action here- http://www.freeactionscript.com/2008/11/drag-drop-snap-inventory-system-v2/

Any help greatly appreciated, thanks!

Fixed it. Rather than modifying this one I wrote my own. Thanks everyone : )

By placing the hit test code on the movie clip "_item" itself, a small array loop sorts it's position on clip event load, and snaps it to the slot. Super easy.
