title: Setting filename property for TOpenFileDialog
body: <p>When I set the Filename property of a TFileOpenDialog and then execute it I see just the final 14 characters of the filename selected in the Filename field.  If I press <kbd>Home</kbd> I can see that the entire string is there, but I'd like it to display properly of course.  I've tested on two Windows 7 and one Windows 8 machine with the same results.  Does anyone have any suggestions or hints on how to solve the issue?</p>
  
  <pre><code>FileOpenDialog1.FileName :=
    'C:\Program Files (x86)\Embarcadero\RAD Studio\9.0\available_downloads_en.htm';
  if FileOpenDialog1.Execute then
    ShowMessage(FileOpenDialog1.FileName);
  </code></pre>
