If keyboard input works at all, it is not likely to be a fundamental problem. However, the working parts probably need races to work. I really miss the LEDs on a keyboard without them. Under WinXP, there is a utility to display the caps lock state using only 10MB of memory. Under FreeBSD, I don't have such bloat and have to fly blind. Bruce
