Initially it wouldn’t connect to the cam. I just ran it again to grab the preview text and it connected to the cam this time.
What I am now seeing in the preview text window says it is grabbing an image. But, the image displayed in webcam capture is not changing from the initial image grab, and the save file is not updating on my harddrive. Other than the static image being displayed it appears that version 10.28 is running along happily even though no image update is occuring.
