For early Leopard adopters that don’t like the new look and feel of the dock, here’s a command to disable that Glass shelf look in your dock:
defaults write com.apple.dock no-glass -boolean YES killall Dock
If you would like to revert the setting:
defaults write com.apple.dock no-glass -boolean NO killall Dock
click on the code and choose run to activate or deactivate this setting
