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

Unsurprisingly, mail problems precluded sending the bug report direct
from windows.  I'm pasting it in here (and attempting a submission to
the bug system), with some addition responses to your questions at the
bottom.

Using Goulet's package on Windows XP.  I unzipped a beta ESS 5.6 over
the existing lisp directory (and some other spots as well when I
started), then unzipped the released 5.5 in the same spot.  Same
behavior either way.  The startup messages indicate I'm picking up the
expected versions.  Here's a recipe with a controlled start up
environment.

Launch command prompt for Windows.  In that prompt...
cd \Program Files\GNU Emacs\bin
emacs.exe -q

Drag the following file, t1.R, into the emacs window:
ta <- "hi there"

In emacs, type esc-x R enter
R 2.10 is the version it selects.
Start it one directory above the t1.R (to avoid saved history and data
in the t1.R directory).
R launches and shows the customary prompts.
In the t1.R buffer type c-c c-l
The display line at the bottom shows
"No ESS process is associated with this buffer now"

While composing this message I revisited t1.R; c-c c-l worked this time
and thereafter.  However, when I restarted emacs and repeated the steps
above, repeated c-c c-l simply repeated the first time error message.

All of of the handful I've tried.

Same problem with 5.5.

See above.  The problem does not seem specific to the development version.
