I'm running Xubuntu. The terminal has started popping up a dialogDo you want to read the Xfce Terminal Manual Online?every time I hit Ctrl+C.  This has rendered emacs (among others) basically unusable, and I can't figure out how to change the configuration.  I haven't played with any config files recently, so I'm not sure why this behavior has started. It's possible that I upgraded the package.Any idea how to disable this?  Where is the relevant setting?If it matters, I use the Dvorak keyboard layout, which occasionally messes up commands.  On the hardware keyboard, the command in question is Ctrl+I.  However, Ctrl+C still works as expected in other programs.
