Vista - Using Vista navigation bar within Files Dialog

I just cant understand why MS have altered the XP setup.
When an app such as Notepad responds to "Open" from
the menu, there is a new way of tracking out of the current
filepath.
Something like this:
"<< Local Disc(C > Media > Misc v"
You have to select between the folders to track forwards and
backwards with difficulty.

I find it completely frustrating. It is not an advance along with
the GUI idea of making things visual and simple. It is not more
complicated but allowing greater functionality.

To move on. I have tried the Classic theme provided which seems
to refer to an Operating System I have never used, in reference to
the specific of my complaint.

Are there any other themes which can emulate my other XP machine?

Thankyou.
