MouseDown vs Click or DblClick

I know the firing sequences for MouseDown vs Click or DblClick. My problem is that when I do a MouseDown I want to drag (MouseDown, MouseMove, MouseUP). When I DblClick, or click (whichever is easier to code, I want to execute something else. I am clicking on a PB.

Yes, it is game. Either I drag a card, or I have the card snap to another destination.

Thanks
