Confirmed on r-devel/Opteron and 1.8.0/K6, so it has likely been with
us for a while. Goes to show how much people actually use that
interface...

(You didn't quite give reproducibility instructions, but 

data(women); fix(women)

and then press Copy etc. will do it.)

BTW, the messed-up screen can be worked around by minimizing and
unminimizing the window.
