[ESS] "No ESS process is associated with this buffer now"

[Martin Maechler]

So it seems
that you (Ross) see the problem 
with Vincent Goulet's version of Emacs + ESS
using Windows XP.

Not such an uncommon setup.
Could other users of this setup help us 
by trying to confirm Ross' problem, please ?

Regards,
Martin Maechler, ETH Zurich
