Both Pc's are win 7 with the same home group. There is nothing installed and it happens outside of the browser as well. We were able to reproduce the issue several times.
I'll copy something, then before I paste I'll have my co-worker copy something, then I'll paste and boom, there it is, what he had copied and not what I had. It also work's in reverse too!
