I have a mirror drive door DP867 that I just installed Panther on (upgrade install from 10.2.5, yeah I was behind on my updates). I'm still using the black/white/clear keyboard that came with the machine... just wondering if anybody knows why my volume up/down/mute and eject keys (the 4 keys in the top right corner) stopped working after the upgrade and if anybody has any ideas how to fix it. Thanks!
