Internet Explorer mouse cursor
– In IE the slider is switching, while something is happening on it with the cursor.
Browsers will slowly eliminate the difference between touching and mouse cursor events, because there are devices nowadays too, what you can get in your hand, and use it with touching, then put it back in it’s container, and then you can use it with a mouse. So the event happening at you is the cursor dragging from left to right or in the other way, which is triggering the slide switching. If you don’t want that, go to the Edit Slider → Controls, and Disable the Touch.
