Tony:

It is indeed most amazing that you have been able to get ESS/Emacs
running under Windows.  And much appreciated by those of us who have to
moil around 
with MessySoft machines.

Thanks to all who have contributed to the effort.

Cheers,

Shawn Boles

It most likely is Windows specific.  It's most amazing that we
actually have ESS/(X)Emacs working under windows in the first place.

Unfortunately, I'm in transit for the next few weeks, but I'll
probably have a windows machine on my desk sometime after that.  Argh.

best,
