I realize that I'm opening the door here, but here goes. After my SL install, I'm getting a strange, seemingly random, "ding dong" doorbell noise. Not related to time of day that I can tell. Maybe a coupe of times per hour, maybe less...very strange. The only other thing I did that I'm aware of is installing iStat pro. I have mail running in the background, but it's not any mail noise that I've heard. Any ideas? (I know, I know..."Someone at the door, "My wife calling me, yada yada...). Go eazy on me please...
