He Ed, Can you debug your problem? To do that: 1. START root session 2. From MS Studio say: "Build" -> "Start debug" -> "Attach to process" 3. Go ahead with your DLL. It should catch the exceptions and you will see the "call stack" (probably) Be aware you should see as many as 3 (or 4) call stacks. You may want to investigate all of them. To do that you may select the target thread via "Debug" ->Threads" menu. Make sure you did not link against of %ROOTSYS%/lib/libNew.lib library. Hope this helps.
