Ok, I seem to have figured out the pattern.  It seems to be something
strange about the way that I'm connecting to the machine.  If I connect
via serial lines and a DECServer (all of out dial-up lines, in several of
our labs), then lynx will not redraw the screen properly.  Connection from
the DECServer is made using telnet (i.e. 'telnet host' from the Local>
prompt).  If I connect directly via telnet to the machine via a PPP
connection (using SLiRP and going through the SAME DECServer), then
suspending works properly.  I'm not sure WHY it behaves this way.  I
tested with TeraTerm in both serial(doesn't work) and TCP/IP modes(works).

Incidentally, pressing ! and returning to lynx does nothing when it messes
up. SIGH...

Any DECServer experts out that that know if something about the telnet
settings could be causing this?  Incidentally, other programs suspend and
resume fine.  Lynx works fine on SunOS (nyx) and Linux boxes on campus,
but none of the HP's... sigh!
