Are you using the iOS companion ?

You are suffering from Sprite Cannibalism.

This sample app solves that problem.

Short answer:
Add a global variable to hold the component block of the last Sprite that had a TouchDown event.
In each drag, check if the sprite component being dragged matches the component in the global variable before responding to the drag.
