There are a to of situations where the above CSS solutions do not work. For instance a transparent fixed header and a sticky footer on the same page. To prevent the top bounce in safari messing things and causing flashes on full screen sliders, you can use this.
if (navigator.userAgent.indexOf('Safari') != -1 && navigator.userAgent.indexOf('Chrome') == -1) {
$window.bind('mousewheel', function(e) {
if (e.originalEvent.wheelDelta / 120 > 0) {
if ($window.scrollTop() < 2) return false;
}
});
}
