I've had an intermittent problem for a while, where for no reason I can deduce, my keyboard volume and mute keys stop working. Logging out will not fix the problem, but a restart will.This started sometime after 10.2.3, and 10.2.4 has apparently not fixed it. I repair permissions regularly, before and after installs, etc.Is anyone else seeing this, and if so, do you know what might be causing it? Could this be related to the spontaneous loss of modifier keys (like shift and spacebar) in Adobe apps? (BTW, according to Adobe techs, Apple has the fix for that in hand, but did not include it in 10.2.4)

Any help will be apprecited.

I didn't find the right solution from the Internet.
