   SlimDX DrawPrimitive only outputs for 32bit compile?
  Hi – I’ve spent the best part of a week porting a big science app from XNA to SlimDX. It all works great for the 32bit compile. However when I compile for 64bit (with 64dll on Windows 7 64bit) the application runs, clears viewport to right color, etc fine but all the same calls to DrawPrimitive display nothing. The application works fine just no graphics showing as 64bit app. I'm using SlimDX's DirectX9 graphics device.Is there something I’m missing about coding or compiling for 64bit?
