The preview stack-list order (Hovering -> List)

Windows XP ordered the list of open windows in a group from newest to oldest, top to bottom. Windows 7 puts the order in the exact opposite - oldest at the top and newest window at the bottom. This wreaks havoc on my habit of knowing where to go when frequently moving from one window to another in a different group. Plus, the location of the main program (i.e. Office Communicator, Outlook inbox, or browser window with default home tabs) is now relative to how many open windows there are in that grouping, whereas before, the main program/first-opened was always placed at the bottom of the list - that made sense. I've searched multiple forums and don't see that Windows 7 offers this as an option. I see there is a way to manually sort this in Taskbar Inspector - or right-click and use "sort group items" to list alphabetically. However my request is for it to behave in the same manner as Windows XP did. I often have a dozen or more programs open and can easily total 40 or more windows open at once. I often use "Alt+Tab" for switching, however when I need to get to a specific window, I count on the preview list and its order arrangement.
