I was doing something with ondbclick and noticed that it fires on the mouse down of the second click.  The spec has this to say

"The ondblclick event occurs when the pointing device button is double clicked over an element. This attribute may be used with most elements."

Is just pushing the mouse down a click? Or is then releasing it to required to complete a "click".  I would think the down and up motion should be required to complete a "click".

A *minimal* testcase would be great.
(I didn't test this yet at all, but click events are dispatched
in ESM during the posthandling of NS_MOUSE_BUTTON_UP)

I might make a test case when I get time.  I am seeing the bug in MinimizeToTray extension I selected the double click to restore option.  The problem being that it fires on the mouse down of the second click, resulting in the mouse up restoring another tray item which is very annoying.

Hallow. my Thunderbird under winXPsp3 behavies like described above:
at starting, or at some loading of CPU work on filters or local archive, every second single-mouse-click treats as double-clicking. so i cant`t just selects some messages - second click forces to open selected messages in their own tabs. it need to awaitng some time to prevent mouse click from accepting as double.
