One thought is that the doc specifies to use a container as a drop target, you must use the backgroundColor property of the container to set a color. Otherwise, the background color of the container is transparent, and the Drag and Drop Manager is unable to detect that the mouse pointer is on a possible drop target. Stephen

I was having trouble dropping a tilelist item onto a canvas. I was able to get the drop to work only if I set the toolTip of the canvas. This seems very odd, like the canvas was not initialized yet. The drag operation starts OK enough but I get the cannot drop marker when I try to drop on the canvas, UNLESS I set the tooltip to something. Any ideas?
