I think it's the last version, "lynx -version" gives
Lynx Version 2.8.5rel.1 (04 Feb 2004)
Similarly, I've tried pushing the down arrow, but it won't let me get to the button that way either.
I guess if the problem is that lynx does not understand the form correctly, that there is little that can be done on the side of the user.
Thanks for trying to help out
