I have an older Logitech QuickCam Express 961322-0403. Is a manual still available? There is a grey button on type (switch type) and I would like to know what it is used for. I hooked up the camera and it works fine. I would just like to learn a little more about it. My email is mooreg@fltg.net. Any information you could give me for this camera I would surely appreciate. Thank you very much. Happy Holidays! Sincerely, G. Moore
