I'm wondering if maybe my keyboard's backlighting isn't working properly. If I have it on, it stays on pretty much all the time - whether I have lights on or not (and yes, it's set to automatically detect light). It's been that way since I got it. But, this morning, I decided to see if the sensor was working in the camera, so I shined a light into the iSight, and the keyboard backlight turned off immediately. Is the sensor maybe just not sensitive enough?
