Hi there Ever since I installed Boot Camp (Win7, 64-bit), the brightness has been extremely high. However, when I use the brightness slider in Control Panel, as well as the brightness buttons on my keyboard, it does nothing! You can move it up and down, but the brightness stays exactly the same. I did a bit of Googling and found a post somewhere about what seemed to be the same issue, which they corrected with an application called "Desktop Lighter". I tried it out, and it works for about half a second, and then the brightness goes right back to where it was (Using Desktop Lighter, it seems to be stuck at about 70%). Does anyone have any ideas? My iMac is in a less-than-well-lit basement, so using Boot Camp (especially at night) is physically painful. All help is appreciated!
