I am typing away in Word (I wouldn't pretend to hit all the keys exactly). Suddenly some of the keys change their function. Home and End are reversed; the space bar does funny things as do the cursors; typing goes in at the beginining of the text instead of at the end. Suddenly as mysteriously as it began it seems to end. Is this something to do with the Asian script facility? I do have an overclocked chip but it has presented no difficulties of this nature until reecently.
