How can I copy some text using the mouse, between two terminal emulator instances, each running its own instance of tmux?
I've read this:

However, I cannot get this to work.
I've tried both the configurations mentioned in the first question, but I'm unable to copy text.

I'm using XFCE as my window manager, xfce4-terminal 0.8.7.4
