RenderTexture not working when in Editor

I’ve come to a point where my code works when compiled and run as standalone, but not when running within the editor.

I was wondering if there is something wrong in my code, or a limitation of some sort that I missed maybe.

Using the following code will work when compiled, but not in the editor.
It’s not a problem, as long as you know it does work in the end…

function TakePreview () {
// creating a Texture to Render to
var myRenderTexture = new RenderTexture(128, 96, 24);
myRenderTexture.Create();

// Setting the Camera to Render to the Texture
Camera.main.targetTexture = myRenderTexture;

// Setting the Texture to be the Active Texture to read from
RenderTexture.active = myRenderTexture;

// Creating a new Texture2D
var myTexture2D = new Texture2D (128, 96, TextureFormat.RGB24, false);

// Wait for the Frame to be fully rendered
yield WaitForEndOfFrame();

// Read pixels from the Render Texture into the Texture 2D
myTexture2D.ReadPixels(new Rect(0, 0, myRenderTexture.width, myRenderTexture.height), 0, 0);
myTexture2D.Apply();

// Reset Camera and Release the RenderTexture
Camera.main.targetTexture = null;
RenderTexture.active = null;
myRenderTexture.Release();

}

I know this will not help, but I have the same exact problem on Unity 5.1.1f1 OSX
