The green Video Chat light has been turning on regularly without me opening it. Sometimes I go into Photo Booth and it won't let me look at or take pictures and an error message comes up basically saying that the camera is in use by another application. I also got locked out of a Yahoo email account that I had created. Additionally, my Blackberry is acting strangely. A few weeks ago, the application Slacker Radio turned up on it and then later on, Bing, NFL and Skype appeared. I never added any of these and am not sure if that means anything, but I'd like your opinions on both matters.
