jQuery Context Menu clashes with jQuery Draggable

将contextmenu源代码改变：

$(this).mousedown( function(e) {
    var evt = e;
    evt.stopPropagation();
    $(this).mouseup( function(e) {
        e.stopPropagation();
        var srcElement = $(this);
        $(this).unbind('mouseup');
        if( evt.button == 2 ) {
            // Hide context menus that may be showing
            $(".contextMenu").hide();

改变为：

$(this).mousedown( function(e) {
    var evt = e;
   if( evt.button != 2 ) {
return;
   }
    evt.stopPropagation();
    $(this).mouseup( function(e) {
        e.stopPropagation();
        var srcElement = $(this);
        $(this).unbind('mouseup');
        if( evt.button == 2 ) {
            // Hide context menus that may be showing
            $(".contextMenu").hide();
