hi there,
when I try to combine mygui with visual leak detector(VLD), VLD reports some memory leak as follows:

leak report:

Was fixed in 3.0.3 long time ago. You can download it there: http://my-gui.svn.sourceforge.net/viewv ... /?view=tar

Hello!
I found one memory leak at MyGUI3.03



	DataFileStream::~DataFileStream()

	{

		if (mFileStream != nullptr)

		{

			mFileStream->close();



			// here 

			delete mFileStream;



			mFileStream = nullptr;

		}

	}

Thank you for reporting. We have leak detection, but usually use Ogre and this leak appears only when Ogre is not used.
Fixed.
