I recall reading that one somewhere too. IIRC, the cause was a keyboard layout mismatch; while sitting down, the user didn't look at the keyboard (typing according to the key positions), and while standing up, the user looked at the keyboard (typing according to the key caps).

Yeah, the 'c' and 'v' keys were switched, IIRC. Which is why it didn't affect some people, but it did for others. Personally, I just cause problems[1] for anyone at my computer who can't touch type :D .

Specifically, that story is told as being first-person from an IBM field engineer*; the issue was that *keys in the user's password* had had their keytops switched while the terminal was being cleaned, and when the user was sitting, he touchtyped the password.

(* That is, when I read it, the writer said "when I was an IBM FE...")
