The right option key is good. But the left one is abnormal. Even I press and hold, the function of option key works sometimes no. I always use the shortcut command+option+control+eject to shut down the computer. But because this keyboard issue, sometimes the computer just restart while I want it to shut down. (the shortcut of restart is command+control+eject) And, besides this, option is actually a pretty useful key. So does anybody else have that problem?
