Dear all,

 using a thread to open the file *.dspx meet an exception which locates in the class mapframe in the function public virtual void Initialize(List<Extent> regions) by the line

Graphics bufferDevice = bufferDevice = Graphics.FromImage(_backBuffer);

Who knows why and can you tell me the solution or give me a tips!
