Greetings. Eeek.. I forgot to upload the patch for that. So sorry.
It's up to 0.09 and the key fix is line #521 or so, fix up the test to

        if (c == 13)
                if (TLJ_A_subbookmark[0])
                        /* TLJ 11/12/96 - bug nailed right about here... */
                        return(0); /* TLJ - assumes default action on ENTER */
                        return (-1);
        if (c == 7)

        if (c == '=') /* let the rest of this function take over and show the 
menu */

                         10. Changes from 0.07 & 0.08

    1. Fixed a bug where just hitting return/enter when adding bookmarks
       would cause a core dump because of an oversight on my part. That
       is now fixed.

    2. Also fixed a STUPID bug when picking bookmarks it would dump if a
       key out of range was selected... I'm testing this release for
       idiot bugs like that...

    3. New: added a feature such that when you define a new sub-bookmark
       description and filename, the first time you add a bookmark to it,
       lynx will include the description of the sub-bookmark in the title
       of the sub-bookmark file.

Problem is array range.. c gets 'A' subtracted from it by c = TOUPPER(c) - 'A'
and then becomes the index for an array... (bonehead bug comes in) 13-'A'
is a negative number... and WHAMO!

Geez :-) I thought I'd get away with that. You know, I wrote it and I
can't track it down (why it happens). I think the part that decides
how many lines to show per screen has some int-division problems.

It's really noticable when you have a 9 row display (I tried), first screen
has 3 entries, second and on ONLY 2...  Shoot me! :-)

Take care.
