Shutter Sound?
At completely random moments my MacBook Pro 5,1 makes the shutter sound like a screenshot. My password_one software makes the exact same noise. I am not engaging either the Mac for a screenshot or the password software. There is no regularity to the sound: not when waking up, or opening lid or closing it, etc. Odd and worrisome. I have searched many times for an answer but have never found one, thus my query to you all. Any ideas on how to determine why the sound happens? THX so much.
MacBook Pro, Mac OS X (10.6.8), 2.4 Ghz Core 2 Duo
