>Description:
When you make the menu format larger than the number of options, the cursor positioning is in the beginning *somewhere*, but not on the options.
If you make the menu format smaller or equal to the number of options, then the cursor is on the options right from the beginning on.
>How-To-Repeat:
Compile the following program, see how it works with ncurses (everything is fine), and that when you use it with nbcurses, it will position the cursor on the right below the last option.
If you change the line
    set_menu_format(menu, 3, 1);
to
    set_menu_format(menu, 2, 1);
the positioning will be right.
