    When I wake my Mac up from sleep, and attempt to change the brightness using the function keys, I see the brightness "image" pop-up on the screen, but when I try to lower it, the brightness doesn't change.
    The boxes quickly go down, but instantly go right back up to the original brightness. Running Mac OS X 10.6.4

    Any ideas? Thanks

    Could it be that feature?

    Or maybe an SMC reset could help.

    I already tried an SMC reset. as for the ambient light sensor - wouldn't it let me lower the brightness since it's dark in the room?

    It should, but maybe it's smegged up??? Do you sometimes cast a shadow onto the iSight camera?

    OK...I unchecked that. I'll give it some time and see if it happens again. Thanks.
