Adobe Air 31 Scroller not working

This is the script. The scrollBar appears and it is not possible to scroll. only by using the scrollbar

<s:List includeIn="State1" contentBackgroundAlpha="0" id="lst" width="100%" height="100%" click="lst_clickHandler(event)" itemRenderer="ActivitiesItemRenderer" >

Hi, sorry for the late reply. The problem exists with the itemrenderer. It apperars a scrollbar at right side. only when touching the top or the bottom of the scrollbar it is possible to scroll.

Hi,

Can you please share your sample application/code where the issue is reproducible so that we can investigate further.

Thanks,
