As far as I'm concerned, this problem came up after having installed a new Asus-Driver for the Webcam. The screensaver and the cam worked greatly together, but LifeFrame always prompted that my Webcam is used by another program. This problem can be easily fixed by using the device manager (Vista: system control --> Device Manager). Just click on the cam device (e.g. USB 2.0 1.3M UVC WebCam), than do a right-click and select properties. After that, left-click on the driver-Tab on the upcoming propertymenu an left-click on deactivate (forth options from above). After having deactivated the device, just simply activate it again (activating the device works the same way as deactivating the device - the only difference ist that the button "deactivate" is labeled "activate" now). As you have done it the problem should be solved. I did this procedure just once and finally LifeFrame2/LifeFrame3 work greatly together with the cam. I hope that I could help you with my post.
