No, the mouse down event doesn't become a click. The point is that the button is actually irrelevant except as a location. It is the mouse down event which does all the work and, of course, if you don't use the mouse, there is no mouse down event. The click is always fired by the button however it is operated. I don't (and won't!!!) use W8 or a touchscreen of any kind but surely there is some kind of "finger down" event equivalent to mouse down otherwise drag and drop etc. would be effectively impossible?
