Some more info on how I finally got the DLL working.
 
1. I used: for Library_Standalone use "encapsulated";
2. I used: Library_Auto_Init use "true";
3. Must NOT use the "-shared" binder switch on either the DLL or the calling application.  Using the -shared switch cause the DLL/app to freeze.

Thanks for your input Dmitry o7
