title: How to show Vista style balloon hints in Delphi?
body: <p>On input validation, I'm using balloon tips instead of message boxes.
  My problem is that on Vista, they have the old XP style with the rounded corners, not the newer more rectangle like appearance.</p>
  
  <p>I've tried creating them using CreateWindowEx and <code>tooltips_class32</code> or showing the Edit's associated balloontip using SendMessageW and <code>EM_SHOWBALLOONTIP</code>, the result is the same.
  Doing the same thing in Visual Studio and C# results in a Vista style balloon tip.</p>
  
  <p>You can see an example of the balloon hint I need, when you toggle Caps Lock while in a password edit, like the one on the Windows Logon.</p>
