Write protection doesn't works with .ppt

There's some bug.

Here is code I use;

//Instantiate a Presentation object that represents a PPT file
Presentation pres = new Presentation();

//....do some work here.....
//Setting Write protection Password
pres.ProtectionManager.SetWriteProtection("test");

//Save your presentation to a file
pres.Save("demoWriteProtected.ppt", Aspose.Slides.Export.SaveFormat.Ppt);

In this case, the file does not protected.

If I choose pptx file format, everything works fine.
