title: Cursor flickers when trying to resize image in RichTextBox
body: <p>I hope this is a simple question. I do the following: </p>
  
  <ol>
  <li>In VS2010, I create a Windows Form Application</li>
  <li>From the Toolbox, drag RichTextBox control to the form</li>
  <li>Size the form and RichTextBox control large enough to display a small picture.</li>
  <li>Run (start debugging).</li>
  <li>Copy a small image from a web browser and paste to richtextbox (using ctrl-v).</li>
  <li>Select the image in the richtextbox.  A resize frame is displayed with small boxes.</li>
  </ol>
  
  <p>Now when I position the cursor over one of the small resizer boxes, the cursor flickers. I see glimpses of the resize arrow cursor but most the time it displays the I-beam cursor.   It does not steadily show the arrow cursors as it does when the a picture is pasted into WordPad and the cursor placed over the one of the small resize boxes.  Should resizing a picture in the RichTextBox behave the same as in WordPad?  How can I stop the cursor flicker?</p>
