That should also work, but I did not do it this way and had no problems after I got the basics right. I have general mousedown and mouseup handlers and use a timeout(~150 ms, but configurable), to determine if we deal with a click, or start dragging (or other things). And on mouseup (or if the mouse leaves the screen) and there is dragging in progress -> stopdrag. So dragging for me ist just one of different special cases ..
