Dragged objects won't snap to target
I've got a simple drag and drop interaction: four drag objects (text boxes bordered and filled with white at 100% transparency) and a stock photo as the designated target. Three of the four should snap to the target one atop the previous so they are readable; the fourth should not snap to the target, but should return to its original position. That drag object has (None) as its drop target. Drag Item Options are set to Return item to start point if dropped outside any drop target. I've set the Drop Target Option to Tile, Stack Random, Stack Offset, and Free, with no change in the behavior of the drag objects: they all (including the wrong choice) snap to the top of the stock photo on top of each other so they are unreadable.
