I have noticed that if there is the slightest movement of the finger when touching an annotation hotspot, it doesn't respond. This is true on my test of desktop browsers as well - if the mouse moves even one pixel during the click, no response from the hotspot. I'm assuming that it is because it thinks you are dragging instead, even if no image rotation occurs. It would be nice if there was some way to adjust the sensitivity of the drag to allow for more sloppy touching/clicking of hotspots.
