        I tried this, exit is now clean.

        I tried the following....

        LYNX -trace         Sent the trace to the file then crashed.
        LYNX -trace -tlog   Sent the trace to the screen then crashed.

Here is some of the trace from the screen output, it seemed more complete.

        I have been using the new version and there are noticable improvements,
particularly on some previously impossible forms. However there still seems to
be a problem with cookies, (ie this has been there a long time but I had 
disabled
cookies), go to a site with a cookie, allow the cookie, then press crtl-K
