Because the script of the button intercepted the mouseDown message.

  btn -> group -> card -> stack

The message hierarchy has several more options than this (see the list
archives), but this applies to what you are doing.

If you want the group mouseDown handler to trigger, you need to remove the
button script, or pass the mouseDown message from the button by adding "pass
mouseDown" to the button's script.
