... hm.  Plot thickens, jumped to a DOS window and that wasn't in the 
path variable though I certainly haven't removed it.  I've tweaked 
the system setting and got it back in... but odd things followed ...

In Xemacs I get a session like that by default as I launch.  I'd love 
not to have that so presumably that means there's something I've got 
in that ess-site.el that is launching that inferior R without waiting 
to be asked.  Maybe that's a problem?  However, that's been the case 
ever since I first installed Xemacs/ESS over a year or so ago I'd 
say.

Xemacs gives:

A subdirectory or file .exe already exists.
Error occurred while processing: .exe.
A subdirectory or file -i already exists.
Error occurred while processing: -i.

Process cmd.exe exited abnormally with code 1

Oh!

Emacs gives:

Xemacs gives: 

`inferior-R-program-name' is a variable declared in Lisp. -- loaded 
from "ess-cust"  

Value: "c:/Program Files/R/rw2001/bin/rterm.exe"

Documentation:
*Program name for invoking an inferior ESS with M-x R.

Emacs gives:
inferior-R-program-name's value is 
"C:\\Program Files\\R\\rw2001\\bin\\Rterm.exe"

Documentation:
*Program name for invoking an inferior ESS with M-x R.

You can customize this variable.

Defined in `ess-cust'.

Interesting.  The plot seems to have thickened.  The other thing that 
has changed, perhaps as a result of that path change but I wonder ... 
is that I can now only get the graphics window inactive for short 
periods, seconds, and I have a hunch that when I have, putting 
another command, even a carriage return, through the inferior R 
process, clears it.

Here's an e.g. that was locking it:

boxplot(PDQTOT ~ TC1,notch=T)

Now it will only do so transiently.  Very weird.

Any further thoughts happily accepted and I'm also happy to reinstall 
any and all of Emacs, Xemacs and ESS as I've no other customisations 
of any of them that would risk being lost.

Thanks very, very much for all this input so far too.
