It sounds like the problem is that you're setup to debug only managed code in your VS 2010 project file. If you're setup to debug only managed you'll get this message if VS is currently executing native code (VS spends a good portion of it's time in native code).
I re-installed Visual Studio 2010 and the SDK. This seemed to work at first, but after changing a source file and launching the Debugger, I was unable to break execution yet again.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
