I'm still having trouble getting a 3rd camera running - I've already got a thread here covering that, so I won't go into too much detail here. Windows XP, first 2 cameras (USB webcams) run a treat, add a third (the Netbook internal camera) and although the camera 'on' light appears on the Netbook, no picture seen in iCamSource and I loose the video from one of my existing cameras when viewing using iCam. When I delete the camera in iCamSource, the light stays on. Reboot the Netbook and iCamSource and my 2 camera work fine.
