Zone Alarm should work with the Security Centre anyway, as far as I know (some earlier builds of ZA had problems, but as long as you are reasonably up-to-date you should be fine). My firewall (Sygate) isn't currently seen by the Security centre, so I've told it to mind its own business until Sygate is updated and all seems well. Running the current (July) nVidia drivers with an FX5200 with no problems, too (but I don't have Max).
