The scroller wraps the MXML you posted? Take out minWidth=0 and put it on
No the scroller is a custom skin class for the s:Application. This code posted is code with in a child of s:Application.
Post the skin. The child you posted had a minWidth of 0 which means that,
if you give it 100% width we'll shrink it all the way to 0 if needed, and
then there will never be a reason to show a horizontalScrollBar.
Ok, figured it out. Thx.
