    window.document.onmouseup = mouseUp
    window.document.ondragstart = mouseStop
}
function mouseDown() {
    if (drag) {
        clickleft = window.event.x - parseInt(dragObj.style.left)
        clicktop = window.event.y - parseInt(dragObj.style.top)
        dragObj.style.zIndex += 1
        move = 1
    }
}
function mouseStop() {
    window.event.returnValue = false
}
function mouseMove() {
    if (move) {
        dragObj.style.left = window.event.x - clickleft
        dragObj.style.top = window.event.y - clicktop
    }
}
function mouseUp() {
    move = 0
}
