Mouse Position at dragDrop event

Question

I'm dragging and dropping items between canvas containers. When I drop an item, the dragDrop event fires. However, I can't seem to find the mouseX and mouseY values of the drop target container, at the point when the item is dropped. Once the mouseDown event fires to start the drag, it seems as though Flex stops capturing the mouseX and mouseY values.
I put a mouseMove event listener on the container where I'm dropping, and as soon as the mouseDown event starts, the mouseMove event stops.
I looked at mouseUp, and while that gives me the correct current mouse position, it is triggered after the dragDrop event, making it too late to use the x and y position of the item I dropped.
How do I find where the point where I dropped the item?

Answer 1

As soon as the mouseDown event is triggered, the mouseMove event no longer triggers. Thank you for the link. I've read that many times while working on this. What it doesn't address is the position of the item dropped. The only way I can think of to get around this is to listen for the mouseUp instead of the drapDrog event, but that should not be necessary. Use the code below, as an example. No matter where you drop the panel in the second canvas, it puts it at the y value of the mouse at the moment the doDrag (or mouseDown) event triggered.
