Some "tools" in Photoshop Elements are "pulled" from Photoshop CS and are "woven" into some other tools, so Adobe has put some measures into Elements to keep people from using the other features thet are for CS use only. You can go to The Hidden Power of Photoshop Elements 7, 6, 5, 4, 3, 2, and 1, by Richard Lynch to release some of these features.
Richard Lynch looks for them since the first appearance of Elements and does his best to unlock them. You can unlock a channel mixer and fusion masks from Elements after you download (it's a freebee) features from his site.
