    David/All,

    I've just installed the Nov10 release on a W98 machine and a W2000pro
    machine hoping to see if the problem I described in 1420 had
    disappeared.

    Unfortunately it might have got worse. On the W98 machine the editor
    works fine, as does triangle, but fkern generates a page fault. On
    the W2000pro machine the same thing happens with an access fault. I
    suspect they both point to a memory problem?

    Has anyone else seen this problem? Perhaps it's something to do with
    my environment or the problem I was trying to solve?

    David, I have the error report from the w2000 machine, where do you
    want me to send it?

    Regards
    Guy Mason
