    All of a sudden, every time I reboot, my screen's brightness is all the way up. So, I go to 'Preferences' and bring it down to only happen again the next time I reboot.
    Not a terrible problem, I hope, but not sure why the settings of this doesn't remain as I left it last. Perhaps I have picked up something OR I have a fault which could get worse?
    Anyone seen anything like this? :confused:

    What computer do you have that doesn't have the F1 and F2 keys set up for screen brightness?
