Hi, I am trying to build and compile ParaView-5.5.1 from source files On Windows by MSVC2013. When I finished the compilation, I found run without debugging works well, but run with debugging is blocked. Eventually, I figured out the block is in a function named UpdatePanel() in which an exception handle code segment was found. When stepping at the “throw false;”, the debugger stopped working. Could you give me some advice? Thank you very much.  
Best regards.

I’m going to assume that you’re in Visual Studio here. You’ll need to select either the `RelWithDebInfo` or `Debug` build types to be able to use the VS debugger on ParaView.
