xrefs to xml not changing to .fm targets

I sure thought this was working last year, and was a major reason for updating to FM9 from FM8.

I use Save Ditamap As... Book 9.0 with fm components.  It converts the components to .fm files alright, but is leaving xrefs poining to the .xml source files rather than to the converted .fm targets.  It's a bit of a pain resetting the references.

Did something get broken?

Is there an option that I'm missing?

Am I mistaken in my belief that this worked last year?  (A real possibility)

Thanks
