Well, I wish I had an answer for you, but I don't. Is it doing it in all programs or just one? A program can disable copy/paste, but if the context menu appears I doubt it is disabled. Just for the heck of it, I'd try the main menu's "edit/copy and edit/paste" or the keyboard shortcuts of ctrl-c (copy) and ctrl-v (paste) and see if either of those work. other than that, I'm at a loss. Hopefully someone is can chime in on this.
