title: Refresh label caption before loading?
body: <p>I have a piece of code:</p>
  
  <pre><code>setEnableControls(false);
  lblLoading.Caption:='Loading tree contents, please wait.';
  someBigLoading(); 
  setEnableControls(true);
  lblLoading.Caption:='';
  </code></pre>
  
  <p>The problem is, the label's caption text doesn't refresh until after the "big loading" is complete. 
  Is there a way to make the program process the message in the message queue, BEFORE going onto the next command?</p>
