regarding earlier versions: I can reproduce this bug with R 3.1.1 on 
Ubuntu 14.04, Gnome Terminal.

I could imagine this is an Ubuntu problem since I've had "ghost mice" 
and strange cursor behavior since I switched to 14.04.


PS: If any Ubuntu user is interested, I was able to fix the problems 
(except for the R bug of course) by turning off the second screen as 
described here:
