How Can I Make TouchEvent.TOUCH_BEGIN work for a Slider?

Hi,

I'm building an application that has a slider. The slider works great using TOUCH_BEGIN, TOUCH_MOVE, and TOUCH_END events. The problem occurs when the user is touching anywhere else on the screen then uses another finger to move the slider at the same time. The slider will not function. The first touch is being detected by the parent of the parent of the slider.

I know it has something to do with a TOUCH_BEGIN event being registered by the first touch. But using evt.touchPointID and setting a touchMoveID value (as suggested in Adobe's docs) doesn't seem to have any affect. Also, setting mouseEnabled to false on the slider.parent.parent clip does not help which I really don't get at all.

Can anyone help me figure this out? Is there a way to ignore the other TOUCH_BEGIN event or a way to prevent it in the first place?

Many thanks!
