title: OnClick and MouseDown not working when using DragMode=dmAutomatic
body: <p>I have a problem with left click on TPanel and TAdvPanel (TMS Components) also. If I set <code>DragMode = dmAutomatic</code> then Left click doesn't work. Right click works.</p>
  
  <pre><code>procedure TMain_Form.Panel_Item_01MouseDown(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
  begin
  if Button = mbLeft then
     begin
       { whatever I type here nothing happen, even showmessage wont popup - no effect}
     end;
  if Button = mbRight then
     begin
       { here code works fine }
     end;
  end;
  </code></pre>
  
  <p>It seems simple to me but ... can't found the way how to resolve this issue and call procedure on left button click. Guys, any idea?</p>
