Onclick and OnUp Triggering Same Time

I have a drag event and i need to trigger a save of its location at the end of dragging so i attach that event to the OnUp and thats fine, however i also use the onClick event to show some detail however now every time i click on the hotspot it also triggers the onUp Event.

This is what i have been working around as there is no DragEnd event i can see from a hotspot.

Thanks in advance.

Even on a click the mouse moves ever so slightly and therefore changes location
