ContentPane and it's Scrollbar - refresh my memory

[w.brants]

That's the API scrollbar you are talking about.
When you create a slider, you can specify thin:true to create a thinner version.

example :

attachMovie('KC8_Slider','slider',1,{_x:20, _y:20, length:100, c:[0xbfbfdf,0xefefff,0xefefff,0x6f6f9f], thin:true});
