esxtop in batch mode does not use config file

I am trying to collect disk statistics using esxtop (resxtop would be fine too), but it appears that it ignores my saved configuration.  If I run it normally, it does read the config file, but not in batch mode.  The resulting file is too large for me to import into Excel.  Anyone else experiencing this?

I suppose I could attempt some post-processing with awk or Perl, but what I really would like is for the program to behave as describe in the documentation and to use the saved config file when in batch mode, just as it does in interactive mode.

Here is my current .esxtop50rc, saved in my home directory on the vMA:

vMA:~> cat .esxtop50rc

ABcDEFghij

aBcDefgHijKLmnOpq

ABCdEfGhijkl

ABcdeFGhIjklmnop

aBCDEFGH

AbcDEFGHIJKLmno

ABCDeF

ABCDe

9u

I have also activated ssh and gone on the ESXi host and run esxtop there, but I get the same behavior.
