Copy / paste in rxvt

Without any chance to test it myself, could it be a vi(m) issue?

I've noticed the behavior on many systems lately, that c'n'p isn't working anymore.
At first I assumed it was xterm, bash, the universe .. But at the end it is an behavior of vim.
So I switched from vim to echo "text" >> file.rc in most cases.
Not very userfriendly, they can forgot a >, write in the wrong file (path), need to know how to set a line break ...
