>Description:
Calling getch() will cause an
implicit refresh() on stdscr.

-- getch(3)

When I move a cursor with move(3) to a new position, it's position is not updated on getch(3).

This works well with ncurses.
>How-To-Repeat:
#include <curses.h>
int
main(int argc, char **argv)
{

	initscr();
	move(10,10);
	getch();
	endwin();

	return 0;
}

>Fix:
N/A

There is a workaround to explicitly call refresh(3) that makes it work.
