        You can try turning on TRACE before the ^Z.  The TRACE messages
use fprintf's to stderr, not screen management via curses or slang
(intentionally), and might include information which helps.  The
suspend, itself, has failed, or Lynx wouldn't be responding to your
keyboard input, but the additional question is why isn't it a clean
failure.  Since you're using fotemods with the Trace Log output as
the default, after the ^Z press ';'.  If that's not displayed either,
'q'uit and look at ~/Lynx.trace directly.
