            Good found.
            Yes seem so.
            I would try it at once as no harm from it.

              @mrjj , in the end I wrote a routine in the C++ that is invokable in the JavaScript, then just replaced all calls to console.info with my own routine, this works well.

                @mrjj , ok, now I'm really confused, after adding my API routine, I can now see using the debugger than messages from JavaScript via the API call and C++ make it into the message handler, I' ve stepped through and the output string contains correct content, but for some reason I do not see the output from the JavaScript API call in the Application Output.

                  @SPlatten, In the message handler, I'm going to push every entry onto a stack then have a separate thread that services the stack popping off the first from the stack.
