Chances are that you had one of those ridiculously high mice that force your wrist to bend upwards ("dorsiflexion"), or otherwise were bending the wrist inappropriately. When mousing, your wrist should be as close to straight as possible. It helps if your mouse has a low profile, so that you can rest your wrist and forearm on the desk and control your mouse with your fingers without bending the wrist. Assuming that you're keeping your wrists straight, then shifting from typing to mousing should reduce the chances of RSI because you are using different muscle groups. But if your mouse position is worse than your typing position, yes, that will probably cause problems... -- Steven -- http://mail.python.org/mailman/listinfo/python-list
