I'm still really confused on your terminology there, Gregg in regards to the Finder. The way I look at it, the Finder is nothing more than Folders that you are opening up. No window that is open on the desktop will have Finder at the top. It's either Computer, Applications, Folder, etc, but there is no such thing as a "Finder" window with the name Finder at the top. Please take a screenshot and show me if there is.
I see the Finder as the environment that allows you to open and view windows. Windows that don't belong to any other program/application are the ones I'm calling Finder Windows.
But, not to stray too far from my question: Have you been able to control where Finder Windows (as defined above - or if you prefer; Folder Windows - is that better) appear in Spaces? I have not.
