I have one more bit of information to add. I have just logged in and clicked into and Emacs X11 window. The cursor in Emacs moved to the place I have clicked onto but it stayed unfilled which means the Emacs X11 window does not have focus. So, it seems like this whole issue has something to do with focus.
