I recently bought the usb "Logitech QuickCam Messenger" webcam to be able to use it with popular instant messaging apps like yahoo messenger, etc. After installing the software, I can access the webcam in "my computer" and it shows live video, but it doesn't work with ANY of my messenger applications. How can I remedy this? I used to have an old bottom-of-the-line logitech webcam with no mic that was very easy to use and messenger apps recognized it easily.
