I have a Macbook pro, so far I have had this problem 3 times, all 3 times I was running Logic pro 9, although i'm not sure if logic is the problem or if it was just a coincidence. Basically most of the keys on my keyboard stop working, all the letters and numbers and characters don't work. the only keys I found to work where the F1-F12 and the delete key. The track pad works fine. And the problem stays after I close logic. The problem stops when I restart my computer. I use logic for an hour or so before the problem happens. Most times I use logic and it doesn't happen. Anyone had the same problem or know what it might be? Thanks, Hanuman EDIT: How stupid am I, I accidentally switched mouse keys on.
