iSight always on

Here's the second Apple wierdness I experienced today. I noticed that the little green light next to the camera on my MacBook is always on. After poking around in Activity Monitor a little bit, nothing came to mind as an obvious program that could be using it. I had a thought that a malicious program was watching me. ;) Sorry, not a lot of excitement here unless you get off on dudes reading documentation and writing code. Anyway, that wasn't it. I seemed to fix it by "resetting the SMC". Here's the link from Apple that led me on my merry way.
