Ahhh! Please help!I have had my MacBook for a little over a year and this problem seems to come and go. Most of the time, the Command C and V shortcuts work properly, they copy and paste text. But sometimes (and constantly the last few days) they act as if I just opened my screen to wake my computer up...ie: I will press the shortcut and my screen goes black, I can hear the hard drive make the noise, and then my password auth. box comes up. When I log in, everything is as it was...this is KILLING me as I use my shortcuts constantly...Thanks in advance.
