Simple Frame code issue

 int main()
{
    VideoCapture vid(0);
    if(!vid.isOpened())
        return 1;
    double rate= vid.get(CV_CAP_PROP_FPS);
    Mat frame,temp;
    namedWindow("temp");
    int delay=2000;
    bool stop(false);
    vid>>temp;
    while(!stop)
    {
     vid>>frame;

imshow("temp",temp);


    if(waitKey(delay)>=0)
        stop=true;

}
imshow("Frame",frame);
imshow("Ex Frame",temp);
Mat dif=(temp - .5 * frame);
imshow("x frame",dif);
vid.release();



waitKey();

return 0;
 }
<\code>
In the above code the 'temp' is acquired before the loop and is shown in the loop and i expected to 
get only the first frame as output but i get the continuous frame output i just cant figure it out
its just as if i've written "imshow("temp",frame);"
Please help..silly thing...big headache...
