    BTW, it never occurred to me to test for this NA/NaN behavior. I'll
    the spreadsheet test scripts in the io package to check for this.

thanks Philip, I'm now wondering if the windows pkg loading was the
difference with seeing/not seeing the bug yesterday.  would that make
this a windows package related bug needing appropriate tests? I'm not
sure how one would write tests capturing cross-package behavior.

Yes the windows pkg is an essential part of the culprit. It provides ActiveX that allows Excel to be invoked through the COM server on Windows.
Whatever it was, it seems the problem has solved itself.
