function _clickVerticalTrackHandler(e) {
    var offset = e.offsetY - this._naturalThumbSizeY * .5,
        thumbPositionPercentage = offset * 100 / this._scrollbarVerticalElement.clientHeight;

    this._viewElement.scrollTop = thumbPositionPercentage * this._viewElement.scrollHeight / 100;

    > this._prevPageY = this._thumbSizeY - e.offsetY + offset; 
    > this._startDrag(e)
}

Also was just gonna suggest this. Tho, with this line instead (in addition to this._startDrag(e)): this._prevPageY = this._naturalThumbSizeY * .5;
