Could it be that you use a very non-standard  R prompt ?
i.e., would it work after

 options(prompt = "> ")

I think that ESS does not have the prompt hard wired,
but I'm pretty sure that
 options(prompt = " ")
would break things..
Did you "accidentally" do that?

Regards,
Martin

When I try this Martin's way, I end up with the same error I get when
