Flex 4 List - scrollbars become visible and cover the itemrenderer

I have a list inside a VDividedBox. When the box is resized so the vertical scrollbar shows on the list, it covers some of the itemrenderers.开发者_如何学C How do I get the list to resize horizontally so that the scrollbar does not cover the renderers?

Actually, I'm fairly sure it's not the list scrollbar that's showing, but the VDividedBox's, hence why it's covering the list. It's a known bug in Flex 3. If I were you, I'd set the height of the list at 100% and remove the scrollbar by doing horizontalScollPolicy="off" on the VDividedBox.
