I have a Aspire One - A0A-150. Crystal One webcam - Not Connected in Yahoo Messenger. Camera source = Crystal One Webcam. Video setting = all default. Everything else seems to be working. I click on the icon in My Computer and see the live video of myself. I ran Movie Maker and could make a video with audio. Upgraded Yahoo IM to Ver 10. Updated the webcam driver (liteon). Updated the BIOS. Still the same. When I click on My Webcam, it says "not connected."
