This _has_ to be an easy AS3 question…doesn’t it?
I am not seeing the below code in MOUSE\_DOWN fired, until I lift the mouse button back up.
This happens even on a new FLA, with only MOUSE\_DOWN, MOUSE\_UP and CLICK handler code – nothing else.
Regardless of what I do, I only see MOUSE\_DOWN, MOUSE\_UP and CLICK traced out AFTER I lift (release) the mouse button…
See code below.
It happens if I attach the handlers to the stage;
or to a sprite.
It happens with/without buttonMode being set.
It happens with/without preventDefault() being called in CLICK…
It happens using event:MouseEvewnt or event:Event as some have suggested.
When I click, I see nothing.
When I release, I see this:
Mouse down
Mouse up
Mouse CLICK
Why don’t I see “Mouse down” when clicking (before releasing)?
What the heck am I missing here?
Thank you!
```auto
stage.addEventListener(MouseEvent.CLICK, function(event:MouseEvent)
{
// event.preventDefault();
trace("Mouse CLICK");
} );
stage.addEventListener(MouseEvent.MOUSE_DOWN, function(event:MouseEvent)
{
// event.preventDefault();
trace("Mouse down");
} );
stage.addEventListener(MouseEvent.MOUSE_UP, function(event:MouseEvent)
{
// event.preventDefault();
trace("Mouse up");
} );
stage.addEventListener(MouseEvent.CLICK, function(event:Event)
{
event.preventDefault();
trace("Mouse CLICK");
_mouse = "click";
} );
_sprite.addEventListener(MouseEvent.MOUSE_DOWN, function(event:Event)
{
// event.preventDefault();
trace("Mouse down");
_mouse = "down";
} );
_sprite.addEventListener(MouseEvent.MOUSE_UP, function(event:Event)
{
event.preventDefault();
trace("Mouse up");
_mouse = "up";
} );
```

Works for me. Maybe something is blocking your trace output? If you put timestamps in your traces, do they show a time gap between down and up?

thank you @senocular
I found the problem.
It was a Logitech wireless keyboard issue (development machine).
The keyboard’s touchpad tap to emulate a click does not trigger a ‘real’ click.
It passes a MouseEvent.CLICK but not a MOUSE\_DOWN (!).
I have never run into something like that before ☹
It was a real pain – as I would not have guessed that could be a problem.
Moved to a different machine and it worked.
Thank you.
