    I have just updated from 10.11 to 10.12 AMD drivers....everything seems to be working well...bench scores etc with futuremark around what i expected as opposed to 10.11 etc etc...

    One thing I have noticed though is that if i put my lappy to sleep, when i resume, the Fn+F5 combo to alter brightness DOWN doesnt work....Fn+F4 will work to increase brightness but not to decrease it.

    Im thinking that this is something to do with sleep resume as i have tested it PRIOR to sleep and both work fine.

    Any one else have this issue? - i did a quick search and found a suggestion to uninstall and reinstall OSD.....dunno if that will work

    Any suggestions welcome! - not that it matters as i dont use it much if at all....tbh, didnt even notice if it worked prior to my new driver install (thats how much i use it lol)

    EDIT: - just tried again resuming from sleep and the darn thing worked now.....dunnno whats up with it.....seems it can be intermittent....

    Ok, so i uninstalled OSD and CC and reinstalled both as I thought it may have something to do with one or the other....NOPE.

    Exactly the same still where it will randomly work upon resuming from sleep.

    No problems adjusting up and down PRIOR to sleep but it gets screwed after.

    Is it just a bug in the OSD/CC that Dell hasnt fixed I wonder?
