title: BalloonHint.ShowHint in Delphi 2010 gets control's hint as title
body: <p>This is my first time using BalloonHints. I'm using Delphi 2010.</p>
  
  <p>I'm not sure I'm using hints properly because in the following scenario, I get a hint with the same text twice: once as title, once as body. I've struggled for some time with this, also referring to other posts here, Delphi's help, and Cantu's example in D2009 Handbook.</p>
  
  <p>I want my code to pop-up a hint if it detects that the user needs to click a button. And I then want to show the same hint if the user mouses over the button later.</p>
  
  <p>In the following sequence, in step 3, the button's hint text is showing up as the title on the balloon text, as if there's a pipe character...</p>
  
  <p>Step 1:  Call ShowHint.  The hint appears properly and then disappears properly.</p>
  
  <p>Step 2:  User moves mouse over button.  The button's hint appears properly.</p>
  
  <p>Step 3:  Call ShowHint again.  The hint that appears has the proper text from the balloon hint's description, BUT it has a title that is from the button.</p>
  
  <pre><code>Procedure TForm.ShowHintIfNeeded.
  var
    Pt: TPoint;
  begin
    if fNeedFileName then
    begin
      BalloonHint1.Description := 'Click this button to open';
      Pt.X := btnOpenFile.Width Div 2;
      Pt.Y := 0;
      BalloonHint1.ShowHint(btnOpenFile.ClientToScreen(Pt));
    end;
  end;
  </code></pre>
  
  <p>and my button's dfm:</p>
  
  <pre><code>object btnOpenFile: TBitBtn
    Hint = 'Click this button to open'
    CustomHint = BalloonHint1
    ShowHint = True
  end
  </code></pre>
