There is nothing abnormal about these gestures. A click is a mouse press and release, it cannot be without both actions.
You don't want to mess with timers, just set a var to true on a mouse down and reset it to false on mouse up and click. if that var is true on the mouse move then start drag. you can keep select on click, and perhaps you need to do something on the start drag like select. All these gestures work as expected. > 1. click Fires the CLICK > 2. double-click Fires the DOUBLE_CLICK event > 3. press and hold (move is optional) press is the MOUSE_DOWN event, hold isn't an event, it's the lack of event. > 4. release Fires the MOUSE_UP event try the above strategy and I think you'll find it's what you are expecting.
