changed file while editing

[mick crane <mick.crane@gmail.com>]

hello
please excuse basic lack of understanding.
I try to write some program in Perl I would find useful.
Use of editing is very basic and usually I get by with vi/vim
recently I try to get used to Nano.
In another virtual terminal if copy one file to another or something, 
the command line words just now got randomly inserted into the file I'm 
editing in other virtual terminal.
Which is distressing.
I'm hoping it's just fat fingers and I managed to make some macro I 
didn't know about.
What bothers me is that it seems random where the words go and wonder if 
opening 2 files in Nano share the same buffer or something and it gets 
mixed up. Is not a problem I saw before.
Any explanation for that ?
