Skulpt tool Painting

Ok, I have been trying to get the skulpt tools painting option to work, but it just dosn’t do anything, it just keeps using the draw tool like normal, I was wondering if this feature is working in 2.49b right now, because I just can’t figure out how to get it to work, so could someone explain this to me, or maybe give me a link to a tutorial that explains this, thanks for any help.
