I bought a MacBook a few months ago. I downloaded the Yahoo messenger just fine. I use the webcam when my boyfriend and I am iming. A few days ago, the messenger just "hangs." I just get that little circle and I can no longer view my webcame at the bottom of my screen. MY BF says he gets my transmission from the webcam just fine as the messenger menu at the top still works. But it bugs me I can't see the image he sees. (Being vain, I want to use flattering angels!) Also when I go to photobooth with the messenger on, the camera does not work. There is a camera icon with a line across it. When I sign out of the messenger, the still camera works just fine. My bf thinks I accidentally clicked on something? Any suggestions?
