EDIT:

Code used so far

void hidepanel()
{
    panel1.Visible = false;
    panel2.Visible = false;
}

private void Form1_Load(object sender, EventArgs e)
{
    hidepanel();
    panel1.Visible = true;
    panel2.Location = new Point(262,19);
    panel1.Location = new Point(0, 0);
}

private void button1_Click(object sender, EventArgs e)
{
    hidepanel();
    panel2.Location = new Point(0, 0);
    panel2.Visible = true;
}

private void button2_Click(object sender, EventArgs e)
{
    MessageBox.Show("2");
}

just add some logic to hide/unhide enable/disable the oposite components. Just like this:

    private void button1_Click(object sender, EventArgs e)
    {
        addLog("Button 1 clicked");
        button1.Enabled = false;
        button2.Enabled = false;
        panel1.Visible = false;
        panel2.Visible = true;
        button2.Enabled = true;
    }

    private void button2_Click(object sender, EventArgs e)
    {
        addLog("Button 2 clicked");
        button2.Enabled = false;
        panel2.Visible = false;
        panel1.Visible = true;
        button1.Enabled = true;

    }

works for me like a charme:

EDIT:
Now, I see the problem, the mouse clicks are enqueued into windows message queue and will fire the click event on button2 although you clicked on a disabled/hidden button1.

I found the solution here: Ignoring queued mouse events

and changed the code to:

        public static void ClearMouseClickQueue()
    {
        win32msg.NativeMessage message;
        while (win32msg.PeekMessage(out message, IntPtr.Zero, (uint)win32msg.WM.WM_MOUSEFIRST, (uint)win32msg.WM.WM_MOUSELAST, 1))
        {
        }
    }
    ...
            private void button1_Click_1(object sender, EventArgs e)
    {
        addLog("Button 1 clicked");
        button1.Enabled = false;
        button2.Enabled = false;
        panel1.Visible = false;
        System.Threading.Thread.Sleep(2000);
        ClearMouseClickQueue();
        panel2.Visible = true;
        button2.Enabled = true;
    }

where PeekMessage etc is defined another class:

    using System;

    using System.Collections.Generic;
    using System.Text;

    using System.Runtime.InteropServices;

    namespace PanelTest
    {
        public static class win32msg
        {
            [DllImport("coredll.dll")]
            [return: MarshalAs(UnmanagedType.Bool)]
            public static extern bool PeekMessage(out NativeMessage lpMsg, IntPtr hWnd, uint wMsgFilterMin, uint wMsgFilterMax, uint wRemoveMsg);

            public enum WM : uint{
                /// <summary>
                /// Use WM_MOUSEFIRST to specify the first mouse message. Use the PeekMessage() Function.
                /// </summary>
                WM_MOUSEFIRST = 0x0200,
                /// <summary>
                /// Use WM_MOUSELAST to specify the last mouse message. Used with PeekMessage() Function.
                /// </summary>
                WM_MOUSELAST = 0x020E,
            }
            [StructLayout(LayoutKind.Sequential)]
            public struct NativeMessage
            {
                public IntPtr handle;
                public uint msg;
                public IntPtr wParam;
                public IntPtr lParam;
                public uint time;
                public System.Drawing.Point p;
            }
        }
    }

Please test.
