(April 2010 15" MacBook Pro/2.66GHz/Core i7/4Gb RAM/OS X 10.6.8 (Build 10K549))

I've got this pref set, but my keyboard backlight insists on going off after an indeterminate (*) period of non-use all the same.

I tried trashing com.apple.systempreferences.plist, which floats to the top when I toggle the pref, and restarting, but all that did was somehow cost me my AirTunes, requiring a re-install of iTunes.

Has anybody got any suggestions?

Thanks.

(*) It went off after 6 minutes a little while ago, and just now it was still on after 15 minutes in precisely the same light.

Edit: Zapped PRAM and reset SMC...no joy. frown
