I have the darnest problem in my os x beta. In the termnal app the backslash key doesn't generate a backslash but seems to act as a deadkey generating four of the key strokes of the key that follows (e.g. worthless). This is on a JIS keyboard G4. Anyone have any idea how I can rewire the keymap (software wise) to fix it? Someone else out there must have the same problem (in Japan anyway).
