I think you can accomplish this with a registry tweak
(To set the GIOPT_NOSETCURDIR bit, see registry.txt).
After that, you will likely want to specify your favorite working directory for the "Start in" directory in the windoze dialog for "properties" of the shortcut you use to start x2.
fred is right, but GIOPT_NOSETCURDIR has severe repercussions throughout the program; all commands executed from the addressbar will be out of (path) context
if you need a fixed console, why not have a regular one opened?
typing a single $ in the addressbar will open a dos box on the current folder
