ECMA 2 File Export Stats Missing

I saw an earlier thread where this was noted as a known issue for Full Export, but I'm seeing the same thing on a simple file-based ECMA 2 running normal (delta) exports. How do I get my ECMA to report export stats? Do I need to mix Call-based and File-based methods? E.g. use IMAExtensible2FileImport to read my file and IMAExtensible2CallExport to write my file if I want stats, or am I missing something?

Cheers,

Dave
