LCD gets stuck(hd44780)

[dongSORRY for reversal)]

hello all, (sorry for reversal of name n topic)

(me posting it again.
sorry if i m troubling with many posts.)
this is dong again.one question.

The problem : According to code LCD should keep displaying
"Dong the king" till it gets 8 bit input.But it doesnot wait for the input for more than 2 seconds.If it gets input in 2 seconds it shows the points.

otherwise it keeps showing "dong the king"(it gets STUCK here)

what i do??

The same is problem from "hello" to input from PIN D0.if it gets input in 1-2 seconds, it moves forward ; otherwise gets stuck at "hello".

is there a way lcd keeps waiting for the inputs.??(and not get stuck)

--------------------------------My code--------------------------------------

while(1)
{
lcd_init();
delay_ms(1000);

printf(lcd_putc,"hello!!!");
delay_ms(1000);
while(input(pin_D0))
{
lcd_init();
delay_ms(1000);

lcd_init();
printf(lcd_putc,"dong the king");
delay_ms(1000);//new

dong= input_b();

while(dong != 255)//My lcd doesnot wait for this for long.it gets stuck.
{
if(points = dong & 0x7F;)
{
printf(lcd_putc,"%u",points);
delay_ms(1000);
}
}
