[ESS] mouse-selecting previous line in *R* buffer

[Dan Davison]

In a *R* buffer, if I hover my mouse pointer over the (not a?) previously evaluated line,
the whole line excluding the R prompt goes sort of light green and a message comes up saying

'mouse 2: insert after prompt as new input'

I'm a bit anti mice. Nevertheless I was trying to use the thing to copy some text from that line,
and the light green message stuff prevented me from selecting the text. I'm not at all claiming
that this shouldn't be default behaviour, but how do I turn this functionality off?

Thanks!

Dan

p.s. The text was destined for another xterm, not an emacs buffer, so I wasn't using emacs kill/yank. 
If anyone has any tips for copying between emacs buffers and xterms and other application windows 
in linux without using the mouse that would be very welcome too (though maybe they should be offline).
