I have a very strange bug with text selection in *RichTextBox* :

I create the following simple form :

```
public partial class Form1 : Form
{
    public Form1()
{
    InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        richTextBox1.Text = "Tempore quo primis auspiciis in mundanum fulgorem surgeret victura dum erunt homines Roma, ut augeretur sublimibus incrementis, foedere pacis aeternae Virtus convenit atque Fortuna plerumque dissidentes, quarum si altera defuisset, ad perfectam non venerat summitatem.";
    }
}

```

When launching the app I can select the text in the *RichTextBox* until I press the control key. 

The *RichTextBox* is then no longer selectable until I click several times outside the application.

I hear about [silly bug with AutoWordSelection](https://stackoverflow.com/questions/3678620/c-sharp-richtextbox-selection-problem) but I tried the trick without success.

I'm using *Framework .Net v4* on *Windows 8*.

Does anyone have an idea about it?
