Richard, LuaXMLRPC seems to be based on the Expat library. In CIN-based form, LuaVIEW cannot dynamically link to external libraries. But you can install Rolf's DLL patch for LuaVIEW. http://www.citengineering.com/LuaVIEW/releases/Windows_DLL1.2.1.zip There is a reasonable chance that that will solve some of the problems you are having.
