   Bug in DXSDK 9 C?
  I'm still looking into this, but I have a bad feeling ID3DXConstantTable::GetConstantByName() is no longer working for top level constants.I've just updated DX to this latest version, and my small demo no longer runs.Can anyone else confirm this?Thanks.   
  Fear not. A re-re-install of it did the trick. Seems like some leftovers from DxSDK9b was causing the problems.Sorry to have caused a scene.
