Re: lynx-dev Lynx 2.8.4rel1 on HP-UX 11i.

[Arne Sagnes]

Thomas,
  thank you for all your replies.  They have been helpful in guiding us
towards a solution that has yet to present itself. :-)  We have a little
more information available now.  The original application that executes
Lynx does not use curses itself.  It uses some Sybase Forms library that
unfortunately is outdated these days.  The application and the execution
of Lynx works well under HP-UX 10.20, which is what it was developed on.
  We were able to reproduce the problem by having the application spawn
a shell, then execute Lynx manually.  The same problem was evident, but
I was unable to find anything different in any 'stty' or environment
settings.  One thing I did notice is that it seems like Lynx doesn't
pick up the "single key press".  For instance, in normal-Lynx you're
able to simply hit "q" for "quit".  In our spawned-Lynx, you must hit
"q", followed by "Enter" for it to acknowledge the key-press.  Does that
give anyone new ideas? :-)  Thanks again for all the help.  We really
appreciate it.

Arne
