[R] R run under Emacs fatal errors halt execution

I am running R.exe/Rterm.exe 2.7.1 under Emacs 22.1 under the DOS shell under Windows XP. (My Cygwin installation is broken!) I am not currently using ESS:

> R.exe --vanilla

   R version 2.7.1 ...
   ...
> 1+1

   2

This works fine until I hit an R error -- pretty much any error -- when the process halts and returns to the shell:

Wrong number of arguments error:

  > quote()
  Error in quote(): 0 arguments passed....   Execution halted

Syntax error:

  > )
  Error: unexpected ')' in ")"
  Execution halted

The same thing happens in R.exe and Rterm.exe.

How do I get R to catch the error and let me continue?

Thanks,

            -s
