按钮点击方法不起作用，因为它的可见性发生了变化

Question

I have a picturebox(called pic_Image) and 2 buttons(called btn_AddImage & btn_RemoveImage). I want to make the buttons visible as user moves the mouse on the pic_Image and make them invisibe as mouse leaves the pic_Image. this is the code for making visible:

private void pic_Image_MouseMove(object sender, MouseEventArgs e)
    {
        btn_AddImage.Visible = true;
        btn_RemoveImage.Visible = true;
    }

and this is the code for making invisible:

private void pic_Image_MouseLeave(object sender, EventArgs e)
    {
        btn_AddImage.Visible = false;
        btn_RemoveImage.Visible = false;
    }

The problem is that after I use the pic_Image_MouseMove method the Onbutton click method doesn't work.

thanks in advance

Mouse movie events continuously fires until mouse is on picture Replace mouse move with mouse enter

private void pic_Image_MouseEnter(object sender, MouseEventArgs e)
{
    btn_AddImage.Visible = true;
    btn_RemoveImage.Visible = true;
    if (pic_Image.Image != null)
        btn_RemoveImage.Visible = true;
}
