All I want in OS X is the Dock folder to work just like 10.4's. So I can click on a folder and it opens up the finder window. no stacks no grids. I mean, the option to.
Hold Command when you click it.
Or, if you really hate the keyboard, right click the folder on the dock and set it to always display using the 'List' view. Then, when you click the folder, the first choice at the bottom of the list is "Open in Finder." It's 2 clicks instead of 1, but it works.
I'd just use the Command method, but at least there's 2 options for you. (EDIT: Looks like clmason came up with an even better option for you.)
