Reading from the title, you will know that I have successfully installed Snow Leopard on my little Black Macbook. As a kick-start, let me share with you this simple trick to enable stack highlighting.
You only need to execute these two lines of Terminal commands to make it happens :
defaults write com.apple.dock mouse-over-hilite-stack -boolean YES
After execution of the second command line, your Dock will be restarted and when you mouse over one of your stack items, it will be highlighted.
Screenshot on the right displays how the stack highlighting looks like.
