My son uses the WASD keys to move up, down. left and right in gaming but, now he has to hold the "Ctrl" or "Alt" key to make it work. Then the space bar won't work with Ctrl or Alt held down, several other keys are not functioning properly also. He also can't type in the chat boxes. We have tried several keyboards, USB and PS2 type. He said it started after he reinstalled his operating system. Anyone with ANY suggestion are appreciated. He downloaded game on one of my computers and it works fine on mine so, it must be his computer. We tried Keytweak to remap keys besides the tools in game to remap keys neither works. He has ask many friends in games he play and several has heard of this problem but, no one knows how to fix it. The keys type correctly in word pad, the problem is when he tries to remap keys in game.
