Need Mouse Position In IE When I Click On L Link

I am facing a problem in getting mouse position when I click on a link, specialy the Y coordinate of the mouse position. I am using this code :

[color=Sienna]if (document.layers) { // Netscape
document.captureEvents(Event.MOUSEMOVE);
document.
} else if (document.all) { // Internet Explorer
document.
} else if (document.getElementById) { // Netcsape 6
document.
}
// Global variables
xMousePos = 0; // Horizontal position of the mouse on the screen
yMousePos = 0; // Vertical position of the mouse on the screen
xMousePosMax = 0; // Width of the page
yMousePosMax = 0; // Height of the page

function captureMousePosition(e) {
if (document.layers) {
xMousePos = e.pageX;
yMousePos = e.pageY;
xMousePosMax = window.innerWidth+window.pageXOffset;
yMousePosMax = window.innerHeight+window.pageYOffset;
} else if (document.all) {
xMousePos = window.event.x+document.body.scrollLeft;
yMousePos = window.event.y+document.body.scrollTop;
xMousePosMax = document.body.clientWidth+document.body.scrollLeft;
yMousePosMax = document.body.clientHeight+document.body.scrollTop;
} else if (document.getElementById) {
xMousePos = e.pageX;
yMousePos = e.pageY;
xMousePosMax = window.innerWidth+window.pageXOffset;
yMousePosMax = window.innerHeight+window.pageYOffset;
}

window.status = "xMousePos=" + xMousePos + ", yMousePos=" + yMousePos + ", xMousePosMax=" + xMousePosMax + ", yMousePosMax=" + yMousePosMax;

}[/COLOR]

It works fine for mouse move and displayes correct mouse pos in status bar.

But when on mouse click i try to get the position it return the xMousePos good, but yMousePos it return is related to the browser client area in IE rather than the my document ( html ).

So when i try to place a div their it is placed near top of the document bcoz it ignores the scrolling information. or the

document.body.scrollLeft

document.body.scrollTop
is always 0( zero ) as i debug it. Code:
