ncurses problem

hi there,

i have a problem using ncurses. i attached the source code with this email.
this program displays two text fields. my problem occurs when i add this,
`char buff[256];` after the declaration, `int ch;`.
after adding the character array declaration, the text fields won't 
display anymore.
any ideas?

    FORM *formp;
    FIELD *fields[2];

    initscr();

    noecho();
    keypad(stdscr, TRUE);

    fields[0] = new_field(1, 32, 4, 18, 0, 0);
    fields[1] = new_field(4, 32, 6, 18, 0, 0);

    refresh();

    mvprintw(4, 5, "IP Address:");
    mvprintw(6, 5, "Message:");
    move(4, 18);
    refresh();

    while( (ch = getch()) != KEY_F(1) )
    {
       switch(ch)

Hey Earl!

try
FIELD *fields[3];
and
fields[2] = NULL;

I wondered how should new_form know when the array ends..

regards,

Markus
