Make a PictureBox visible / not visible using MouseHover

I think this is a stupid question, but I don't understand what is happening here.

I use this code:

   private void pictureBox1_MouseHover(object sender, EventArgs e)
    {
        pictureBox1.Visible = false;
        pictureBox1.BackColor = Color.Black;
    }

    private void pictureBox1_MouseLeave(object sender, EventArgs e)
    {
        pictureBox1.Visible = true;
    }

The problem is: The picturebox changes color to black if mouse is over picturebox, but the visibility doesn't change. Why?

You can use MouseEnter event instead of MouseHover and bool field isHover that you can use in attempt to reduce flickering :

public partial class Form1: Form
{
    bool isHover = false;

    private void pictureBox1_MouseEnter(object sender, EventArgs e)
    {
        if(isHover) return;
        // with MouseHover this control visibility appears to be locked with MouseEnter it is not
        pictureBox2.Visible = false;
        pictureBox2.BackColor = Color.Black;
    }

    private void pictureBox1_MouseLeave(object sender, EventArgs e)
    {            
        if(!isHover) return;
        isHover = false;
        pictureBox2.Visible = true;
    }

...

}

I think your problem is as soon as you hover the picture it really disappears (that's why you see the back color turn to black, the event is firing). However the picture disappears which lead to situation where your mouse is not on the picture anymore, therefore Mouse_Leave event firing.
