title: Keep NSWindow front
body: <p>I open a NSWindow from my main NSWindow.</p>
  
  <pre><code>DropHereWindowController *dropHereWindowController = [[DropHereWindowController alloc] initWithWindowNibName:@"DropHereWindow"];
  [dropHereWindowController showWindow:nil];
  </code></pre>
  
  <p>I want this window to stay on top of my main window when dragging a file from the finder to that "DropHereWindow". However when opening the finder (not having the focus any longer) my "DropHereWindow" goes behind my main window. </p>
  
  <p>I tried orderFront, makeKey, makeKeyAndFront but nothing helped.
  What can I do about it?</p>
