title: how to update a Rebol3 GUI from a network event
body: <p>I have written a test <a href="https://github.com/gchiu/RSOChat/blob/master/r3gui-network-test.r3" rel="nofollow">GUI application</a> to see how to update a R3-GUI from a network event.</p>
  
  <p>The server port receives the event from a client, but using</p>
  
  <pre><code>set-face window-inputarea msg
  </code></pre>
  
  <p>fails to update the GUI unless I also mouse over or otherwise generate a GUI event.  This then seems to kick off outstanding event handling.</p>
  
  <p>Do I need to send a simulated GUI event to allow this to happen programatically or is there another way?</p>
