title: Multiple types in a SaveFileDialog filter
body: <p>In my SaveFileDialog I have multiple types in the filter, however when viewing the dialog if I choose a filter to view files of that type in the directory I am only able to see files for the first and last filters.</p>
  
  <pre><code>    bool save;
      SaveFileDialog dlg = new SaveFileDialog();
      dlg.FileName = "*";
      dlg.DefaultExt = "bmp";
      dlg.ValidateNames = true;
  
      dlg.Filter = "Bitmap Image (.bmp)|*.bmp|Gif Image (.gif)|*.gif |JPEG Image (.jpeg)|*.jpeg |Png Image (.png)|*.png |Tiff Image (.tiff)|*.tiff |Wmf Image (.wmf)|*.wmf";
      save = (bool)dlg.ShowDialog();
  
      if (save)
      {
          SaveImage(dlg.FileName);
      }
  </code></pre>
  
  <p>I can see files of type .bmp and .wmf
  If I change the order of the filters I can always only see the first and last.</p>
