avoid click event when pano is dragged

Hello, I'm implementing an script where the user has the ability to add a hotspot to the panorama when clicking on it. So far it's working great, however I'm having a hard time differencing between a user click and a user drag... What's happening right now is that when the user drags the panorama, almost always a click event is launched at the final position of the mouse. How could I avoid that?

No. it wasn't on a touch device, I am testing on the krpano web viewer web viewer. I'll try updating also, Thanks...
