Thanks, Deirdre. I'll check out Firefox on Windows to see if I can duplicate that copy/paste problem.
I've just done the above copy/paste with Flock (which is Firefox based). Is that what you meant you couldn't do? I know that I've never (either this version of Scope) or the older one, been able to do that when I'm in this screen (i.e. with the message above & me writing my comments), but I've been able to do it from the view when you can see all the messages. I guess that's because you might want to quote from "Fred" while replying to "jane". However, it does mean that if you hit "reply" to Fred's message & then want to quote him, with the appropriate citation at the top (so as to make it clear for those who read messages sorted by date, rather than threaded), you have to go back to the previous screen.
It would be really nice if you could get the citation when you copy from the message list, or in the reply mode.
From memory, to activate it in the first place, you have to click ctrl+s, or something. Can't quite remember now
