This change refers to the auto movement of the property slider.

In js/control.js around line 90 there is this code

if (autoscroll_slider!==0){
setInterval(function(){
slider_control_left_function(element);
}, autoscroll_slider
);
}

replace that with

if (autoscroll_slider!==0){
setInterval(function(){
slider_control_right_function(element);
}, autoscroll_slider
);
}
