Try to look in the List.scroller or List.scroller.viewport properties.

 List control to have the labels that line up with my itemrenderer elements.
 Things work great until my list requires scrolling. Then the 16 pixel
 scrollbar throws things out of whack.

 I could probably make a simple adjustment if I could detect the presence of
 the scrollbar on the list component and adjust my header elements
 accordingly. I just haven't been able to figure out how to do that yet.

 Anyone dealt with this?

Allmas,

Thanks! - that's exactly where I ended up - this was basically a Flex 4 
learning curve issue.
