IE11 mouse drag is turned off, but slide is still switching

Error

At the Slider settingsControls the Mouse drag option is turned off, but in IE11 the slider still can be switched with the mouse cursor.

Solution

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 its container, and then you can use it with a mouse. So the cause of your problem is that the Touch event is turned on too here at the Controls, and if you don't want this to happen, turn it off.
