Visual Studio 2012, Win 7 64bit current, IE 10
I created a Form with a WebBrowser control and navigated to Yahoo. Double clicked on the word "one" and it works fine.
Please BEWARE that I have NO EXPERTISE! Also, I've been told by an expert, that when you post an image it clutters up the thread and mysteriously, over time, the link to the image will somehow become unstable or something to that effect. :) I can only surmise that is due to Global Warming of the threads.

Your code causes the same error as my code.
Therefore, it must be something different about your machine.
Do you have IE 10 installed?
I can reproduce the problem using VS 2010 using .Net 3.5 and 4.0.
I can reproduce the problem using VS 2012 using .Net 4.5.

If I run YOUR code inside a fresh Win7 Pro x86 install, I get the problem. I don't think its something running inside my app as my whole app is only about 10 lines of code.
If the problem were mouse settings, I would think the behavior would not be different inside a VM simply by installing IE 10.
The reason I'm so hung up on IE 10 is that before I install it, everything is fine. Same everything and literally the ONLY change is installing IE 10 and the problem behavior starts happening. Super-reproducible.
Since IE 10 is the ONLY change, that must be involved in the problem in some way.
Here is my version of VS2012...
Just for the sake of clarification, this IS what you're unable to do, correct? If so, I've already confirmed no issues...
Option Strict On Public Class Form1 Friend WithEvents uc1 As New MyUserControl With {.Parent = Me} Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load uc1.LoadHTML("<html><body><center>This is a test interesting is it not?</center></body></html>") End Sub End Class Public Class MyUserControl Inherits UserControl Friend WithEvents Webbrowser1 As New WebBrowser With {.Parent = Me, .Dock = DockStyle.Fill} Public Sub LoadHTML(html As String) WebBrowser1.DocumentText = html Webbrowser1.Document.Body.SetAttribute("contentEditable", "false") End Sub End Class

It would be nice to have a real solution and not someone just marking something as the solution without trying the code I went to the trouble to post.
I have failed to reproduce the error following your exact steps more than once. I have gone through the trouble to explain that I am unable to reproduce your error. I believe this error is specific to your system or installation. Here is a screenshot of your error not happening, in 2010 as well.
Public Class Form1 Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click UserControl1.LoadHTML("<html><body>This is a test interesting is it not?</body></html>") End Sub End Class
Public Class UserControl Public Sub LoadHTML(ByVal html As String) WebBrowser1.DocumentText = html Do Until WebBrowser1.ReadyState = WebBrowserReadyState.Complete Application.DoEvents() Loop WebBrowser1.Document.Body.SetAttribute("contentEditable", "false") End Sub End Class

I do wish you would spend the 10 minutes ...
This has not been a 10 minute task. So I hope you actually appreciate the effort put into this.
Following your EXACT procedure:
1. Create a new VB.Net project in VS 2010, targetting .Net 3.5
2. Create a usercontrol <--- this step is the key
3. Add a webbrowser to the usercontrol
4. Add this code to the usercontrol
(See your original post)
5. Add that control to a form
6. Add a button to the form with the following button.Click event:
(See your original post)
7. Run the project and click the button
8. Then, try to double-click the word "interesting" and notice it does not select.I produced the following results on the following variations of Windows 7 professional(clean installs, mind you).
I suggest maybe trying with a different mouse.
Windows 7 Professional (32bit) With Visual Studio Ultimate 2010:
- Internet Explorer 8 - Pass
- Internet Explorer 10 - Pass
Windows 7 Professional (64bit) With Visual Studio Ultimate 2010:
- Internet Explorer 8 - Pass
- Internet Explorer 10 - Pass
Screenshots(the red area is the client rectangle of the usercontrol to show that the webbrowser is not docked:

64 Bit
