Just got my new Blackbook, and I have a few questions. When going through the welcome/start up process, the picture for the account page came up, however when I went to go use the isight the screen was blank. Thats OK I continued on and finished everything with all the updates, however now the isight doesn't show a a picture. The effects all just have a colored screen now a picture. How do I remedy this. The green isight light is on, so the camera should be on, or is this just a mistake. Thank you for any help!
