IIRC, the python int type has different lengths on windows and linux 64 bit systems. And what about 3.0? I think we probably need to do something here, but I'm not sure what. The different behavior of the numpy double and integer types corresponding to the python types as opposed to the rest of the scalar types is an issue that has annoyed me since forever. Chuck
