I just upgraded to MacOS 10.6.8 yesterday, and since then, the screen on my Macbook is acting strange. 


I'm hooked up to an external monitor which I use almost all the time as the primary monitor.  Usually, when I'm using the external, I turn the brightness all the way down (to black) on the Macbook.  After the update, however, the Macbook seems to have a mind of its own.  The screen gets brighter, then dimmer, then brighter again, without reason.  Or, othertimes, after about 30 seconds of inactivity, the Macbook screen gets brighter, then when you move the mouse, it goes back to black again.


It's not that I care so much, but just wish I knew what was going on.  Glitch in the new software?
