Question

c#上的PictureBox跟着鼠标移动，结果有时动有时不动

代码如下，是从网上看到的：
bool leftFlag;
private void pbRbing1_MouseDown(object sender, MouseEventArgs e)
{
leftFlag = true;
}

private void pbRbing1_MouseMove(object sender, MouseEventArgs e)
{
if (leftFlag==true)
{
pbRju1.Location = new Point(MousePosition.X,MousePosition.Y);
}
}

private void pbRbing1_MouseUp(object sender, MouseEventArgs e)
{
if (leftFlag == true)
{
leftFlag = false;
}
}

具体什么情况下不动呢？比如和鼠标速度与移动的位置有关？可以帮调试
