It wont; you're not refreshing the background.

Unsurprising, as werase() erases the contents of the window.

It won't; refresh() copies stdscr to the terminal, but you're not
erasing stdscr. Call `erase()' or `werase(stdscr)' prior to calling
refresh(), e.g.
#include <curses.h>
#include <unistd.h>
int main(void)
{
WINDOW *w;
int i;
initscr();
w = newwin(1, 20, 0, 0);
waddstr(w, "Hello, world!");
for (;;)
for (i = 0; i < 25; i++)
{
mvwin(w, i, i);
erase();
refresh();
wrefresh(w);
napms(50);
}
endwin();
return 0;
}
