shot in the dark, but maybe your at the wrong access level in the o/t control panels. at least through os 8.6, the o/t control panels have their own access controls. look under the edit menu, see if there's an option called 'user mode' that might be the thing. either you're not in the right user mode, or there was a password on the 'administrator' user, or something like that.
just an idea,
