I was having the exact same problem. The way I fixed this is by adding
document.viewport.getScrollOffsets()[1] to the
withinIncludingScrolloffsets function in the prototypejs library.
withinIncludingScrolloffsets: function(element, x, y) {
var offsetcache = Element.cumulativeScrollOffset(element);
this.xcomp = x + offsetcache[0] - this.deltaX;
this.ycomp = y + offsetcache[1] - this.deltaY -
document.viewport.getScrollOffsets()[1];
this.offset = Element.cumulativeOffset(element);
return (this.ycomp >= this.offset[1] &&
this.ycomp < this.offset[1] + element.offsetHeight &&
this.xcomp >= this.offset[0] &&
this.xcomp < this.offset[0] + element.offsetWidth);
}
