Hello, I have a multimedia keyboard, it haves keys for play/stop music, open media player... and others for open: web navigator and mail client . The first group of keys works well, they control WMP, but the navigator and mail client keys doesn't work. It isn't a keyboard problem, on my other XP installation they work well. I am customizing a XP Professional SP2, integrating drivers for audio and wifi, integrating some updates (up to november 2006), unnatended installation and deleting some components; but I haven't deleted any keyboard driver/language. Thanks
