I have a problem with the new beta of FaceTime for Mac. Right now, all I can do with it is display a window of my webcam. I can't click on Preferences in the menu bar and I also notice that "Sign Out" is grayed out. I haven't entered an Apple ID because I wasn't prompted for one. I have recently checked Apple Software Update and I have all updates installed. I also have OS X 10.6.4 installed. Any ideas? P.S.: Take a look at the attachment and you might be able to get what I mean.
