When capturing onMouseDown the event.button property gets the wrong value when
left button is clicked. The left button should set button property of the event
to 1, currently its set to 0. The right button has the correct value of 2.
Reproducible: Always
Steps to Reproduce:
1. goto http://dahlman-group.com/bug.html
2. click on the text with left button
3. an alert pops up telling you the value of the button-property
4. The value is 0 for mozilla 0.9 and 0.91 and 1 for Opera5, IE5, Netscape6
Actual Results: The value is 0 for mozilla 0.9 and 0.91 and 1 for Opera5, IE5,
Netscape6
Expected Results: The value should be 1 as it is for Opera5, IE5, Netscape6

}
function init() {
document.onmousedown = clickCheck;
}
</script>
</head>
<body onload="init();">
<div >Hello, please click me. <br>
Left mousebutton should be 1 and the right should be 2
<br><br>This page does not work in Netscape 4 and only left button
works in Opera.<br>
But demonstrates the problem for IE5+ Netscape6+ and Mozilla 0.9/0.91

Excerpt from
http://www.w3.org/TR/2000/REC-DOM-Level-2-Events-20001113/events.html#Events-MouseEvent
Attributes:
button of type unsigned short, readonly
During mouse events caused by the depression or release of a mouse button,
button is used to indicate which mouse button changed state. The values for
button range from zero to indicate the left button of the mouse, one to indicate
the middle button if present, and two to indicate the right button. For mice
configured for left handed use in which the button actions are reversed the
values are instead read from right to left.
Moz is doing this correctly.
Summary: When capturing onMouseDown the event.button property gets the wrong value when left button is clicked. → When capturing onMouseDown the event.button property gets the wrong value when left button is clicked.
