You never specify what version of 386/ix you are running, but if I am not
mistaken this is one of the most significant bug fixes (in my opinion) in
2.02. At least it was the real motivating reason to install the upgrade
from 2.01 for me.

In any case, this bug is old news, if you had called ISC they would have
informed you of the fix (at least Santa Monica would've, not sure about
that east coast office :-).
