>(Lynx with curses behaves correctly).

        It shouldn't be behaving that way.  The code for getting
the screen columns and rows at startup is in start_curses() called
from setup(), both in src/LYCurses.c.  For slang, it's using that
library's SLtt_get_terminfo() function.  That should have set
slang's SLtt_Screen_Rows, to which LINES is defined in LYCurses.h,
and slang's SLtt_Screen_Cols, to which COLS is defined.  Lynx in turn
sets it LYlines and LYcols to LINES and COLS.  The LYlines and Lycols
values are updated in conjunction with each new page display via
size_change() in src/LYUtils.c.  Whatever is going wrong on HP-UX 9.05,
and on whatever system Thanh is using, must be happening in those
functions, if not in the slang library itself.  If it's a problem in
Lynx, the best bet is size_change().
