New window in Leopard but not in Tiger!
I already mentioned a feature that lets you go anywhere in the path of a folder in the Finder. It is by holding down "Command" and clicking on the title of the folder in the Finder window top bar. The path pops up and you can choose exactly where you want to go back. Once the path pops up, whether you keep on holding Command or not in Tiger, the result is the same. It redirects you to the folder that you chose. In Leopard however, you have to release the Command key before selecting where you want to go or it will open it in a new window. I think the way it works in Leopard makes more sense, at least you have the choice of getting it in a new window or not. I just wasn't used to it and I kept getting new windows, but now I know!
