Wrong Screen size in editor mode

Unity Engine
1

Hi there.
I’ve got the problem.
Screen.width and Screen.height both return wrong values in my custom editor.
Here is my very simplified code:

File Editor/ScrSizeEditor.cs

using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomEditor(typeof(ScrSize))]
public class ScrSizeEditor : Editor
{
    public override void OnInspectorGUI()
    {
        Debug.Log(string.Format("Screen size at edit-time: {0}x{1}", Screen.width, Screen.height));
    }
}

File ScrSize.cs

using UnityEngine;
using System.Collections;

[ExecuteInEditMode]
public class ScrSize : MonoBehaviour
{
    void Update()
    {
        Debug.Log(string.Format("Screen size at runtime : {0}x{1}", Screen.width, Screen.height));
    }
}

The output is:
Screen size at runtime : 1024x768
and
Screen size at edit-time: 464x947

Why this happened?
What have I missed?
Either there is a bug?

I’m using Unity 4.6.1p2 on PC with windows 8.1.

Thanks.

There’s no bug and nothing is wrong. The screen size refers to the game view window size in the editor.
